This study demonstrates the synthesis of locust bean gum-cl-poly (acrylonitrile) based hydrogel were obtained using acrylonitrile monomer, MBA as crosslinker and APS as initiator by involving free radical co-polymerization and crosslinking reaction technique. The factors influencing the adsorption capacities, including the initial concentrations of dye solutions, contact time, initial pH values and dosage of the adsorbent as well as ionic strength of the solution are discussed. The locust bean gum-cl-poly(acrylonitrile) based hydrogel was found to be pH sensitive. The kinetics studies show that the adsorption of the dye fitted a pseudo-second-order equation.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/41161183" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="2fe76e1bb47281e620c91d8fa195e8c2" rel="nofollow" data-download="{"attachment_id":61403069,"asset_id":41161183,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/61403069/download_file?st=MTczMjUyMDA3Miw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="11740108" href="https://yeungnam.academia.edu/DrSadanandPandey">Dr Sadanand Pandey</a><script data-card-contents-for-user="11740108" type="text/json">{"id":11740108,"first_name":"Dr Sadanand","last_name":"Pandey","domain_name":"yeungnam","page_name":"DrSadanandPandey","display_name":"Dr Sadanand Pandey","profile_url":"https://yeungnam.academia.edu/DrSadanandPandey?f_ri=834747","photo":"https://0.academia-photos.com/11740108/4125320/31357380/s65_dr_sadanand.pandey.jpg"}</script></span></span></li><li class="js-paper-rank-work_41161183 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="41161183"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 41161183, container: ".js-paper-rank-work_41161183", });

Many authors have applied the linear form of the PSO model and concluded that such a kinetics is better fitted, based on the values of adsorption capacity at the equilibrium (qe) and the high value (which should be close to 1.0) of the coefficient of determination (R2). The linearized PFO model is usually ruled-out because the values of qe and R2 are worse than those obtained by the linearized PSO. On the other hand, the nonlinear fitting of data is highly recommended for the use of equations that are not typically linear such as kinetics data. In this communication, the data of 52 articles (containing 225 experiments of adsorption kinetics) were collected, and the kinetic data were treated using the linear and nonlinear PFO and PSO models. Results indicated that the values of k2 (the rate constant of the PSO model) calculated from the nonlinear fitting method were quite different from those acquired from the linear one.

Many authors have applied the linear form of the PSO model and concluded that such a kinetics is better fitted, based on the values of adsorption capacity at the equilibrium (qe) and the high value (which should be close to 1.0) of the coefficient of determination (R2). The linearized PFO model is usually ruled-out because the values of qe and R2 are worse than those obtained by the linearized PSO. On the other hand, the nonlinear fitting of data is highly recommended for the use of equations that are not typically linear such as kinetics data. In this communication, the data of 52 articles (containing 225 experiments of adsorption kinetics) were collected, and the kinetic data were treated using the linear and nonlinear PFO and PSO models. Results indicated that the values of k2 (the rate constant of the PSO model) calculated from the nonlinear fitting method were quite different from those acquired from the linear one. However, the values of qe2 (adsorption capacity at the equilibrium of the PSO model) are in complete agreement, which induces users to an erroneous decision. Using a linearized kinetic model, all the 225 values of R2 of the PSO model were closer to 1.0 than PFO. However, when nonlinearized fitting of the data was used, 122 out of 225 cases (54.22%) showed that the nonlinear PFO is better fitted than the PSO kinetic model.","downloadable_attachments":[],"ordered_authors":[{"id":15699985,"first_name":"Farooq","last_name":"Sher","domain_name":"independent","page_name":"FarooqSher","display_name":"Farooq

It was found that the sorption of a particular ion by Na-CLI increases with the increase in the initial concentration of the solution of that ion. At a given initial concentration, the sorption degree increases with temperature. Also, the sorption of a particular ion is greater when the initial solution contains a second ion than it is when the particular ion is present alone. The sorption kinetics is in accord with the pseudo-second-order reaction rate model. The values of the k 2 rate constant do not show a regular change with the initial Zn 2+ /Ni 2+ concentrations probably because the presence of the second ion has a significant effect on the reaction rate. Thermodynamic study has shown that the sorption is exothermic, occurring spontaneously in the 298-318 K range and with a positive entropy change.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/51547602" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="de7198bd858935e1e7b7a55ce681254c" rel="nofollow" data-download="{"attachment_id":69226248,"asset_id":51547602,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/69226248/download_file?st=MTczMjUyMDA3Miw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="21287673" href="https://independent.academia.edu/StevanStupar">Stevan Stupar</a><script data-card-contents-for-user="21287673" type="text/json">{"id":21287673,"first_name":"Stevan","last_name":"Stupar","domain_name":"independent","page_name":"StevanStupar","display_name":"Stevan Stupar","profile_url":"https://independent.academia.edu/StevanStupar?f_ri=834747","photo":"/images/s65_no_pic.png"}</script></span></span></li><li class="js-paper-rank-work_51547602 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="51547602"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 51547602, container: ".js-paper-rank-work_51547602", });

It was found that the sorption of a particular ion by Na-CLI increases with the increase in the initial concentration of the solution of that ion. At a given initial concentration, the sorption degree increases with temperature. Also, the sorption of a particular ion is greater when the initial solution contains a second ion than it is when the particular ion is present alone. The sorption kinetics is in accord with the pseudo-second-order reaction rate model. The values of the k 2 rate constant do not show a regular change with the initial Zn 2+ /Ni 2+ concentrations probably because the presence of the second ion has a significant effect on the reaction rate. Thermodynamic study has shown that the sorption is exothermic, occurring spontaneously in the 298-318 K range and with a positive entropy change.","downloadable_attachments":[{"id":69226248,"asset_id":51547602,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":21287673,"first_name":"Stevan","last_name":"Stupar","domain_name":"independent","page_name":"StevanStupar","display_name":"Stevan Stupar","profile_url":"https://independent.academia.edu/StevanStupar?f_ri=834747","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":55543,"name":"Zeolites","url":"https://www.academia.edu/Documents/in/Zeolites?f_ri=834747","nofollow":false},{"id":113095,"name":"Adsorption and wastewater treatment","url":"https://www.academia.edu/Documents/in/Adsorption_and_wastewater_treatment?f_ri=834747","nofollow":false},{"id":217322,"name":"Natural Zeolites","url":"https://www.academia.edu/Documents/in/Natural_Zeolites?f_ri=834747","nofollow":false},{"id":650671,"name":"Clinoptilolite","url":"https://www.academia.edu/Documents/in/Clinoptilolite?f_ri=834747","nofollow":false},{"id":834747,"name":"Adsorption Kinetics","url":"https://www.academia.edu/Documents/in/Adsorption_Kinetics?f_ri=834747"},{"id":3608482,"name":"Adsorption Thermodynamics","url":"https://www.academia.edu/Documents/in/Adsorption_Thermodynamics?f_ri=834747"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_8023956" data-work_id="8023956" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/8023956/Impregnation_of_palm_shell_activated_carbon_with_polyethyleneimine_and_its_effects_on_Cd2_adsorption">Impregnation of palm shell activated carbon with polyethyleneimine and its effects on Cd2+ adsorption</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Palm shell activated carbon (AC) was impregnated with low (LMW) and high molecular weight (HMW) polyethyleneimine (PEI) via batch adsorption.

The maximum amount of LMW PEI adsorbed on AC was determined to be approximately 425 mg/g carbon while the maximum adsorbed HMW PEI was 2.8 mg/g carbon. The LMW PEI adsorption data fitted the Langmuir isotherm better than the Freundlich isotherm. The PEI impregnated AC were characterized via nitrogen adsorption, scanning electron microscopy, elemental analysis, thermogravimetric, Fourier transform infra red and pH drift analyses. Only LMW PEI could be successfully impregnated as monolayers on the surface of the micropores. This impregnation leads to drastic reduction of surface area and pore volume whereas impregnation of HMW PEI does not significantly affect the physical characteristics of the AC. LMW PEI impregnation appears to enhance Cd2+ adsorption capacity of the AC while HMW PEI impregnation is found to have an opposite effect. This result shows that LMW PEI impregnation technique may have the potential to improve the batch adsorption capacity of AC for other transition metal ion adsorption as well. © 2007 Elsevier B.V.

Usage of ISE was very appropriate for real-time adsorption kinetics data collection as it facilitated recording of adsorption data at very specific and short time intervals as well as provided consistent kinetics data. Parameters studied were initial Pb(II) concentration and agitation speed. It was found that increases in initial Pb(II) concentration and agitation speed resulted in higher initial rate of adsorption. Pseudo first-order, pseudo second-order, Elovich, intraparticle diffusion and liquid film diffusion models were used to fit the adsorption kinetics data. It was suggested that chemisorption was the rate-controlling step for adsorption of Pb(II) onto PSAC since the adsorption kinetics data fitted both the pseudo second-order and Elovich models well. © 2007 Elsevier Ltd.

Usage of ISE was very appropriate for real-time adsorption kinetics data collection as it facilitated recording of adsorption data at very specific and short time intervals as well as provided consistent kinetics data. Parameters studied were initial Pb(II) concentration and agitation speed. It was found that increases in initial Pb(II) concentration and agitation speed resulted in higher initial rate of adsorption. Pseudo first-order, pseudo second-order, Elovich, intraparticle diffusion and liquid film diffusion models were used to fit the adsorption kinetics data. It was suggested that chemisorption was the rate-controlling step for adsorption of Pb(II) onto PSAC since the adsorption kinetics data fitted both the pseudo second-order and Elovich models well. © 2007 Elsevier Ltd.

Present study was aimed to remove lead and copper from aqueous media using Fumaria indica biomass as a function of metal ions initial concentration. Both metal removal was investigated in single and binary system. For comparison isotherm models i.e., Langmuir and Freundlich were applied on experimental adsorption data. Results showed that the copper behavior was different in single and binary metal system, whereas lead adsorption remained the same in both single and binary metal systems. The Freundlich isotherm model fitted well to the adsorption data of both single and binary metal system. The thermodynamic parameters i.e., ∆G 0 , was measured to get insight into adsorption phenomenon and negative value of ∆G 0 suggest that the adsorption process was spontaneous in nature. Results showed that in multi-metal system the adsorption of specific metal ion may change and during metal adsorption from industrial wastewater this effect must be taken in account before generalization of results.

A dual resistance rate model incorporating intrinsic adsorption kinetics and film diffusion was used to assess the relative importance of the two rate processes under varying experimental conditions. Intraparticle diffusion was not accounted for in this model since metal uptake by nonliving algal biomass is a passive nonmetabolically mediated process and is, therefore, a surface binding phenomenon. Modeling results have found that film diffusion appears to be the rate-limiting step at low initial metal concentrations. On the other hand, both the intrinsic adsorption kinetics and film diffusion are likely to control the overall rate of adsorption at high initial metal concentrations. The model described in this study can thus be used for predicting if and under which conditions the metal adsorption process could sufficiently be described by single resistance models. <br /> <br /><a href="http://online.liebertpub.com/doi/pdfplus/10.1089/109287504773087318" rel="nofollow">http://online.liebertpub.com/doi/pdfplus/10.1089/109287504773087318</a></div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/7761564" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="0b470c6283d940d617a95173f10cd72c" rel="nofollow" data-download="{"attachment_id":34276208,"asset_id":7761564,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/34276208/download_file?st=MTczMjUyMDA3Miw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="13958389" href="https://malaya.academia.edu/MohdAliHashim">Mohd Ali Hashim</a><script data-card-contents-for-user="13958389" type="text/json">{"id":13958389,"first_name":"Mohd Ali","last_name":"Hashim","domain_name":"malaya","page_name":"MohdAliHashim","display_name":"Mohd Ali Hashim","profile_url":"https://malaya.academia.edu/MohdAliHashim?f_ri=834747","photo":"https://0.academia-photos.com/13958389/4018074/4690936/s65_mohd_ali.hashim.jpg"}</script></span></span></li><li class="js-paper-rank-work_7761564 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="7761564"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 7761564, container: ".js-paper-rank-work_7761564", });

study, activated carbon (ACBA) was fabricated from Balanites aegyptiaca seed shell (BASS) using a two-step H 3 PO 4 activation approach and was tested for the adsorption of toxic hexavalent chromium [Cr(VI)] from simulated wastewater. The surface properties, morphology, and elemental composition of the prepared ACBA were examined via Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD) and Brunauer-Emmett-Teller (BET) surface area analyses. The influence of various operating conditions such as pH, adsorbent amount, contact time and temperature was investigated. Kinetic studies indicated that the pseudo second order model was able to provide a realistic description of the adsorption kinetics and that film diffusion was the dominating mechanism of the sorption process. The adsorption activation energy evaluated using kinetic data suggested physical nature of Cr(VI) adsorption onto the carbon surface. Thermodynamic investigation confirmed that the adsorption was spontaneous and endothermic in nature. Regeneration tests demonstrated that 0.2 M NaOH can appreciably desorb Cr(VI) from Cr(VI)-loaded ACBA and the regenerated adsorbent can be used for six successive adsorption-desorption cycles while sustaining an adsorption efficiency of 80.10%.

The surface properties, morphology, and elemental composition of the prepared ACBA were examined via Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction (XRD) and Brunauer-Emmett-Teller (BET) surface area analyses. The influence of various operating conditions such as pH, adsorbent amount, contact time and temperature was investigated. Kinetic studies indicated that the pseudo second order model was able to provide a realistic description of the adsorption kinetics and that film diffusion was the dominating mechanism of the sorption process. The adsorption activation energy evaluated using kinetic data suggested physical nature of Cr(VI) adsorption onto the carbon surface. Thermodynamic investigation confirmed that the adsorption was spontaneous and endothermic in nature. Regeneration tests demonstrated that 0.2 M NaOH can appreciably desorb Cr(VI) from Cr(VI)-loaded ACBA and the regenerated adsorbent can be used for six successive adsorption-desorption cycles while sustaining an adsorption efficiency of 80.10%. Altogether, the ACBA showed high adsorptive performance, fast kinetics and reuse potential, indicating the suitability of its application in wastewater treatment.","downloadable_attachments":[{"id":65723018,"asset_id":45148709,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":72487307,"first_name":"Musa","last_name":"Husaini","domain_name":"independent","page_name":"MusaHusaini2","display_name":"Musa Husaini","profile_url":"https://independent.academia.edu/MusaHusaini2?f_ri=834747","photo":"https://0.academia-photos.com/72487307/42460170/34063219/s65_musa.husaini.jpg"},{"id":88829970,"first_name":"Umar","last_name":"Yunusa","domain_name":"buk","page_name":"UYunusa","display_name":"Umar Yunusa","profile_url":"https://buk.academia.edu/UYunusa?f_ri=834747","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":522,"name":"Thermodynamics","url":"https://www.academia.edu/Documents/in/Thermodynamics?f_ri=834747","nofollow":false},{"id":3340,"name":"Reaction Mechanisms","url":"https://www.academia.edu/Documents/in/Reaction_Mechanisms?f_ri=834747","nofollow":false},{"id":834747,"name":"Adsorption Kinetics","url":"https://www.academia.edu/Documents/in/Adsorption_Kinetics?f_ri=834747","nofollow":false}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_42976146" data-work_id="42976146" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/42976146/Adsorption_Kinetics_for_CO_2_Capture_using_Cerium_Oxide_Impregnated_on_Activated_Carbon">Adsorption Kinetics for CO 2 Capture using Cerium Oxide Impregnated on Activated Carbon</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Various metal oxides of CeO 2 , ZnO, and Co 3 O 4 impregnated on activated carbon (AC) were synthesized to determine the CO 2 capture efficiency and analyse with adsorption kinetics model.

The original design consisted in a metal screen tube concentrically inserted into a copper tube; grains of solid adsorbent are fitted between the two tubes. Two experimental setups were used to measure the degree of contribution provided by radial adsorbate flow through the metal screen on adsorption kinetics: the first setup was composed by a tube fully filled with adsorbent, resulting in mainly axial adsorbate flow, while the second one was composed by an external tube with an internal, coaxial metal mesh tube leading to free adsorbent flow lengthwise, resulting in predominant radial flow through the adsorbent bed. The adsorption working pair was constituted by silica gel and water. This particular pair is preferred for adsorption chillers due to its superior thermodynamic characteristics. Temperature and mass measurements were made along the adsorption process to compare the heat and mass transfers obtained with each reactor configuration.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/18078899" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="10094f2265f51213004cc54fd2b60efc" rel="nofollow" data-download="{"attachment_id":39864211,"asset_id":18078899,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/39864211/download_file?st=MTczMjUyMDA3Miw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="26141186" href="https://ufpb.academia.edu/PauloVodianitskaia">Paulo Vodianitskaia</a><script data-card-contents-for-user="26141186" type="text/json">{"id":26141186,"first_name":"Paulo","last_name":"Vodianitskaia","domain_name":"ufpb","page_name":"PauloVodianitskaia","display_name":"Paulo Vodianitskaia","profile_url":"https://ufpb.academia.edu/PauloVodianitskaia?f_ri=834747","photo":"https://0.academia-photos.com/26141186/7184492/11883660/s65_paulo.vodianitskaia.jpg"}</script></span></span><span class="u-displayInlineBlock InlineList-item-text"> and <span class="u-textDecorationUnderline u-clickable InlineList-item-text js-work-more-authors-18078899">+2</span><div class="hidden js-additional-users-18078899"><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://independent.academia.edu/Jos%C3%A9Gurgel">José Gurgel</a></span></div><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://independent.academia.edu/herbertmelo1">herbert melo</a></span></div></div></span><script>(function(){ var popoverSettings = { el: $('.js-work-more-authors-18078899'), placement: 'bottom', hide_delay: 200, html: true, content: function(){ return $('.js-additional-users-18078899').html();

Adsorption data were fitted to four established adsorption kinetics models, namely, pseudo-first-order, pseudo-second-order, Elovich equation and intraparticle diffusion. It was found that PEI impregnation at 16.68 and 29.82 wt% PEI/AC increased the Pb2+ uptake rate while the opposite was observed for PEI impregnation at 4.76 and 8.41 wt% PEI/AC. The increased uptake rates were due to higher concentration of PEI molecules on the surface of clogged pores as well as varying pore volumes. The adsorption kinetics data fitted the pseudo-second-order model better than the pseudo-first-order model, implying chemisorption was the rate-controlling step.

The use of super-absorbent polymers offers effective ways of saving water in agriculture. However, before selecting a suitable polymer, determining of an appropriate model is essential.<br />Materials and Methods: In this study, the water absorption model was evaluated by two super-absorbent polymers from polyacrylamide family, abbreviated as T-A200 and T-A100. The experiment was carried out with four replicates and water absorption was recorded by the polymers in different times until reaching the equilibrium swelling (stable inflation), as instantaneous and cumulative. After testing the free swelling, the absorption kinetics of fluid (the changes in the absorption of water by the gel time) was determined by immersion in water. After that the result was presented by a graph that depicted the changes in the ratio of absorbed solvent in time to this solvent in equilibrium in time. Also, the trend of solvent absorption by the two polymers in time measured. To determine the mechanism of penetration, the mentioned model used and the values of n and k were calculated.<br />Results: The results showed that the fluid absorption in heterogeneous environments such as gels was associated with significant deformation. The graph shows that in all cases n was less than 5.0, and therefore the mechanism of transfer of the solvent into the polymer network follows the Fick's law.<br />Conclusion: the appropriate super-absorbent polymers in agriculture must be able to absorb maximum amount of water at the minimum time; therefore, doing so will prevent from the loss of rainfall or irrigation water applied. To prove it, the model should follow the Fick diffusion which penetration rate is lower than the speed of molecular relaxation, and only diffusion phenomena is effective through the transfer of ground-penetrating, so, molecular relaxation phenomenon does not affect on the transfer of ground-penetrating. Consequently, after any deformation or swelling, the polymers quickly reached a new balance and stresses will quickly vanish; therefore, it does not have any effect on the speed of penetrating component. In this study, the penetration of the fluid into the polymer followed the Fick model. Hence, this model would certainly be recommended to periodic swelling ability in agricultural purposes.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/68514870" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="5d303a6dfc8ffc22884acd5c9c250d38" rel="nofollow" data-download="{"attachment_id":78961980,"asset_id":68514870,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/78961980/download_file?st=MTczMjUyMDA3Miw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="211719042" href="https://gausca.academia.edu/jwsc">Journal of Water and Soil Conservation</a><script data-card-contents-for-user="211719042" type="text/json">{"id":211719042,"first_name":"Journal of","last_name":"Water and Soil Conservation","domain_name":"gausca","page_name":"jwsc","display_name":"Journal of Water and Soil Conservation","profile_url":"https://gausca.academia.edu/jwsc?f_ri=834747","photo":"https://0.academia-photos.com/211719042/71000721/59623103/s65_journal_of.water_and_soil_conservation.jpg"}</script></span></span></li><li class="js-paper-rank-work_68514870 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="68514870"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 68514870, container: ".js-paper-rank-work_68514870", });

therefore, appropriate and productive management and the application of efficient methods in order to maintain enough water in the soil for optimum utilization of scarce water resources is necessary in the long run. The use of super-absorbent polymers offers effective ways of saving water in agriculture. However, before selecting a suitable polymer, determining of an appropriate model is essential.\nMaterials and Methods: In this study, the water absorption model was evaluated by two super-absorbent polymers from polyacrylamide family, abbreviated as T-A200 and T-A100. The experiment was carried out with four replicates and water absorption was recorded by the polymers in different times until reaching the equilibrium swelling (stable inflation), as instantaneous and cumulative. After testing the free swelling, the absorption kinetics of fluid (the changes in the absorption of water by the gel time) was determined by immersion in water. After that the result was presented by a graph that depicted the changes in the ratio of absorbed solvent in time to this solvent in equilibrium in time. Also, the trend of solvent absorption by the two polymers in time measured. To determine the mechanism of penetration, the mentioned model used and the values of n and k were calculated.\nResults: The results showed that the fluid absorption in heterogeneous environments such as gels was associated with significant deformation. The graph shows that in all cases n was less than 5.0, and therefore the mechanism of transfer of the solvent into the polymer network follows the Fick's law.\nConclusion: the appropriate super-absorbent polymers in agriculture must be able to absorb maximum amount of water at the minimum time; therefore, doing so will prevent from the loss of rainfall or irrigation water applied. To prove it, the model should follow the Fick diffusion which penetration rate is lower than the speed of molecular relaxation, and only diffusion phenomena is effective through the transfer of ground-penetrating, so, molecular relaxation phenomenon does not affect on the transfer of ground-penetrating. Consequently, after any deformation or swelling, the polymers quickly reached a new balance and stresses will quickly vanish; therefore, it does not have any effect on the speed of penetrating component. In this study, the penetration of the fluid into the polymer followed the Fick model. Hence, this model would certainly be recommended to periodic swelling ability in agricultural purposes.","downloadable_attachments":[{"id":78961980,"asset_id":68514870,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":211719042,"first_name":"Journal

Adsorption capacities of the adsorbents were determined at varying adsorption temperatures by using thermogravimetric analysis (TGA). CO2 regeneration was successfully performed at 400°C, indicating the adsorbents were feasible with CO2 adsorption and desorption processed. 0.1Bi/AC was shown as the most efficient adsorbent at optimum adsorption temperature of 30°C with CO2 adsorption capacity of 58.71 mg CO2/g adsorbent. Although the BET surface area of 0.1Bi/AC was reduced (783.25 m2/g) compared to AC only, the Bi2O3 loading noticeably enhanced CO2 chemisorption due to the affinity to attract CO2. The adsorption kinetics indicated that chemisorption dominated the adsorption process as the data fitted well in the pseudo-second-order kinetic model. The stability of CO2 capture capacity was consistent over 5 cycles, with slightly higher than AC only, ascribed to the chemical adsorption by interactions of carbonate species with Bi2O3 besides the physisorption on AC.  These features exhibited a potential for large scale applications of the adsorbent, which favored ambient conditions for CO2 adsorption and feasible desorption process.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/42815949" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="fef10907da8943ac6760d2250799f2e7" rel="nofollow" data-download="{"attachment_id":63046295,"asset_id":42815949,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/63046295/download_file?st=MTczMjUyMDA3Miw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="25928676" href="https://upm.academia.edu/AzizulHakimLahuri">Azizul Hakim Lahuri</a><script data-card-contents-for-user="25928676" type="text/json">{"id":25928676,"first_name":"Azizul Hakim","last_name":"Lahuri","domain_name":"upm","page_name":"AzizulHakimLahuri","display_name":"Azizul Hakim Lahuri","profile_url":"https://upm.academia.edu/AzizulHakimLahuri?f_ri=834747","photo":"https://0.academia-photos.com/25928676/7111313/8124402/s65_azizul_hakim.lahuri.jpg"}</script></span></span></li><li class="js-paper-rank-work_42815949 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="42815949"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 42815949, container: ".js-paper-rank-work_42815949", });

Adsorption capacities of the adsorbents were determined at varying adsorption temperatures by using thermogravimetric analysis (TGA). CO2 regeneration was successfully performed at 400°C, indicating the adsorbents were feasible with CO2 adsorption and desorption processed. 0.1Bi/AC was shown as the most efficient adsorbent at optimum adsorption temperature of 30°C with CO2 adsorption capacity of 58.71 mg CO2/g adsorbent. Although the BET surface area of 0.1Bi/AC was reduced (783.25 m2/g) compared to AC only, the Bi2O3 loading noticeably enhanced CO2 chemisorption due to the affinity to attract CO2. The adsorption kinetics indicated that chemisorption dominated the adsorption process as the data fitted well in the pseudo-second-order kinetic model. The stability of CO2 capture capacity was consistent over 5 cycles, with slightly higher than AC only, ascribed to the chemical adsorption by interactions of carbonate species with Bi2O3 besides the physisorption on AC. These features exhibited a potential for large scale applications of the adsorbent, which favored ambient conditions for CO2 adsorption and feasible desorption process.","downloadable_attachments":[{"id":63046295,"asset_id":42815949,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":25928676,"first_name":"Azizul Hakim","last_name":"Lahuri","domain_name":"upm","page_name":"AzizulHakimLahuri","display_name":"Azizul Hakim Lahuri","profile_url":"https://upm.academia.edu/AzizulHakimLahuri?f_ri=834747","photo":"https://0.academia-photos.com/25928676/7111313/8124402/s65_azizul_hakim.lahuri.jpg"}],"research_interests":[{"id":18469,"name":"Activated carbon adsorption","url":"https://www.academia.edu/Documents/in/Activated_carbon_adsorption?f_ri=834747","nofollow":false},{"id":36338,"name":"CO2 Storage","url":"https://www.academia.edu/Documents/in/CO2_Storage?f_ri=834747","nofollow":false},{"id":39753,"name":"Activated Carbon","url":"https://www.academia.edu/Documents/in/Activated_Carbon?f_ri=834747","nofollow":false},{"id":43832,"name":"CO2 capture and storage","url":"https://www.academia.edu/Documents/in/CO2_capture_and_storage?f_ri=834747","nofollow":false},{"id":391257,"name":"Bismuth Oxide","url":"https://www.academia.edu/Documents/in/Bismuth_Oxide?f_ri=834747"},{"id":397515,"name":"CO2 sequestration","url":"https://www.academia.edu/Documents/in/CO2_sequestration?f_ri=834747"},{"id":531318,"name":"CO2 capture","url":"https://www.academia.edu/Documents/in/CO2_capture?f_ri=834747"},{"id":834747,"name":"Adsorption Kinetics","url":"https://www.academia.edu/Documents/in/Adsorption_Kinetics?f_ri=834747"},{"id":2417026,"name":"Carbon Capture, Oxy-fuel Combustion; CO2 Adsorption and separation, Leak detection","url":"https://www.academia.edu/Documents/in/Carbon_Capture_Oxy-fuel_Combustion_CO2_Adsorption_and_separation_Leak_detection?f_ri=834747"}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_29710128" data-work_id="29710128" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/29710128/Chitosan_derived_Iron_Oxide_Systems_for_Magnetically_Guided_and_Efficient_Water_Purification_Processes_from_Polycyclic_Aromatic_Hydrocarbons">Chitosan-derived Iron Oxide Systems for Magnetically-Guided and Efficient Water Purification Processes from Polycyclic Aromatic Hydrocarbons</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">Chitosan and pyrolyzed chitosan, acting as protective frameworks of magnetic nanoparticles (magnetite/maghemite and/or metallic Fe) have been investigated to be used in magnetically-guided water remediation processes from polycyclic... <a class="more_link u-tcGrayDark u-linkUnstyled" data-container=".work_29710128" data-show=".complete" data-hide=".summarized" data-more-link-behavior="true" href="#">more</a></div><div class="complete hidden">Chitosan and pyrolyzed chitosan, acting as protective frameworks of magnetic nanoparticles (magnetite/maghemite and/or metallic Fe) have been investigated to be used in magnetically-guided water remediation processes from polycyclic aromatic hydrocarbons (PAHs). Chitosan-derived magnet-sensitive materials were first obtained by a one-step co-precipitation method, then two carbon-derived magnetic chitosan materials were obtained under N2 gas flow at 550°C and 800°C, respectively. The obtained materials were investigated by means of X-ray diffraction (XRD), FTIR spectroscopy, Scanning Electron Microscopy (SEM), High Resolution Transmission Electron Microscopy (HRTEM), Atomic Force Microscopy (AFM), Magnetic Force Microscopy (MFM), and magnetization measurements. Thermal treatment conditions, along with the amounts of chitosan used in the synthesis processes, played a critical role in the crystal structure and magnetic properties of the obtained nanomaterials. The adsorption capacity of chitosan-derived magnet-sensitive materials was tested towards PAHs. The results indicate high sorption capacity for anthracene and naphthalene onto the chitosan-derived material pyrolyzed at 550°C. Furthermore, experiments performed with a mixture of eight PAHs show that PAH molecules with higher hydrophobicity and more extended aromaticity had stronger sorption capacity.

With nitrilotriacetate (NTA) anions inclusion as ligand, which is incorporated as interlayer anion in the LDH structure via ion-exchange or coprecipitation reaction, this inclusion would give the Zn-Al LDH material considerable potential as chelate for metal cation contaminants in the aqueous environment by changing the regular behavior of anion exchange to cationic exchanger or serpent. The characterization of the new sorbent is carried out by FTIR spectroscopy (FT-IR), powder x-ray diffraction and scanning electron microscope (SEM). The potential capacity of uptake of Ni(II) and Pb(II) at pH of 5 is attributed to the complex formation between metal ions and NTA in the interlayer of LDH as well as surface adsorption. This work aimed to investigate the kinetics of the sorption mechanism using batch technique at different temperature, pH and various metal concentrations. In addition to the kinetic study of adsorption isotherms and the interaction of adsorbent-adsorbate time as parameters, using a pseudo-first-order, pseudo-second-order and intra-particle diffusion kinetic models. The results show better correspondence to a pseudo-second-order kinetics model with high correlation coefficients (R 2 = 0.997 for the initial concentrations). The model of Freundlich is appropriate to describe the experimental adsorption results with sorption capacities of 7.153, 6.807 mg/g for Ni(II) and Pb(II) respectively. These behaviors are attributed to the structural construction of the Zn-Al-NTA material. All these results have shown the high efficiency of Zn-Al-NTA adsorbent for the fast removal of Ni(II) and Pb(II) from aqueous solution.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/28335493" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="39ffa9989d07275f5760fc5baba2bc04" rel="nofollow" data-download="{"attachment_id":48668334,"asset_id":28335493,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/48668334/download_file?st=MTczMjUyMDA3Myw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="26158770" href="https://independent.academia.edu/RasheedJamhour">Rasheed Jamhour</a><script data-card-contents-for-user="26158770" type="text/json">{"id":26158770,"first_name":"Rasheed","last_name":"Jamhour","domain_name":"independent","page_name":"RasheedJamhour","display_name":"Rasheed Jamhour","profile_url":"https://independent.academia.edu/RasheedJamhour?f_ri=834747","photo":"/images/s65_no_pic.png"}</script></span></span><span class="u-displayInlineBlock InlineList-item-text"> and <span class="u-textDecorationUnderline u-clickable InlineList-item-text js-work-more-authors-28335493">+3</span><div class="hidden js-additional-users-28335493"><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://yu.academia.edu/ababneh">Taher S Ababneh</a></span></div><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://ttu-jo.academia.edu/GhassabSuadi">Ghassab M Al-Mazaideh</a></span></div><div><span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a href="https://independent.academia.edu/TaghreedJazzazi">Taghreed Jazzazi</a></span></div></div></span><script>(function(){ var popoverSettings = { el: $('.js-work-more-authors-28335493'), placement: 'bottom', hide_delay: 200, html: true, content: function(){ return $('.js-additional-users-28335493').html();

With nitrilotriacetate (NTA) anions inclusion as ligand, which is incorporated as interlayer anion in the LDH structure via ion-exchange or coprecipitation reaction, this inclusion would give the Zn-Al LDH material considerable potential as chelate for metal cation contaminants in the aqueous environment by changing the regular behavior of anion exchange to cationic exchanger or serpent. The characterization of the new sorbent is carried out by FTIR spectroscopy (FT-IR), powder x-ray diffraction and scanning electron microscope (SEM). The potential capacity of uptake of Ni(II) and Pb(II) at pH of 5 is attributed to the complex formation between metal ions and NTA in the interlayer of LDH as well as surface adsorption. This work aimed to investigate the kinetics of the sorption mechanism using batch technique at different temperature, pH and various metal concentrations. In addition to the kinetic study of adsorption isotherms and the interaction of adsorbent-adsorbate time as parameters, using a pseudo-first-order, pseudo-second-order and intra-particle diffusion kinetic models. The results show better correspondence to a pseudo-second-order kinetics model with high correlation coefficients (R 2 = 0.997 for the initial concentrations). The model of Freundlich is appropriate to describe the experimental adsorption results with sorption capacities of 7.153, 6.807 mg/g for Ni(II) and Pb(II) respectively. These behaviors are attributed to the structural construction of the Zn-Al-NTA material. All these results have shown the high efficiency of Zn-Al-NTA adsorbent for the fast removal of Ni(II) and Pb(II) from aqueous solution.","downloadable_attachments":[{"id":48668334,"asset_id":28335493,"asset_type":"Work","always_allow_download":false}],"ordered_authors":[{"id":26158770,"first_name":"Rasheed","last_name":"Jamhour","domain_name":"independent","page_name":"RasheedJamhour","display_name":"Rasheed Jamhour","profile_url":"https://independent.academia.edu/RasheedJamhour?f_ri=834747","photo":"/images/s65_no_pic.png"},{"id":53132851,"first_name":"Taher","last_name":"Ababneh","domain_name":"yu","page_name":"ababneh","display_name":"Taher S Ababneh","profile_url":"https://yu.academia.edu/ababneh?f_ri=834747","photo":"/images/s65_no_pic.png"},{"id":39749765,"first_name":"Ghassab","last_name":"Al-Mazaideh","domain_name":"ttu-jo","page_name":"GhassabSuadi","display_name":"Ghassab M Al-Mazaideh","profile_url":"https://ttu-jo.academia.edu/GhassabSuadi?f_ri=834747","photo":"https://0.academia-photos.com/39749765/11055327/14914465/s65_ghassab.suadi.jpg"},{"id":66832513,"first_name":"Taghreed","last_name":"Jazzazi","domain_name":"independent","page_name":"TaghreedJazzazi","display_name":"Taghreed Jazzazi","profile_url":"https://independent.academia.edu/TaghreedJazzazi?f_ri=834747","photo":"/images/s65_no_pic.png"}],"research_interests":[{"id":725583,"name":"Layered Double Hydroxides","url":"https://www.academia.edu/Documents/in/Layered_Double_Hydroxides?f_ri=834747","nofollow":false},{"id":834747,"name":"Adsorption Kinetics","url":"https://www.academia.edu/Documents/in/Adsorption_Kinetics?f_ri=834747","nofollow":false},{"id":1256859,"name":"Adsorption Isotherms","url":"https://www.academia.edu/Documents/in/Adsorption_Isotherms?f_ri=834747","nofollow":false}]}, }) } })();</script></ul></li></ul></div></div><div class="u-borderBottom1 u-borderColorGrayLighter"><div class="clearfix u-pv7x u-mb0x js-work-card work_24346301" data-work_id="24346301" itemscope="itemscope" itemtype="https://schema.org/ScholarlyArticle"><div class="header"><div class="title u-fontSerif u-fs22 u-lineHeight1_3"><a class="u-tcGrayDarkest js-work-link" href="https://www.academia.edu/24346301/Adsorption_Kinetics_of_Methylene_Blue_onto_Clay_Fractionated_from_Bijoypur_Soil_Bangladesh">Adsorption Kinetics of Methylene Blue onto Clay Fractionated from Bijoypur Soil, Bangladesh</a></div></div><div class="u-pb4x u-mt3x"><div class="summary u-fs14 u-fw300 u-lineHeight1_5 u-tcGrayDarkest"><div class="summarized">The adsorption kinetics of methylene blue (MB) from aqueous solution onto clay fractionated from Bijoypur (Netrokona) soil based on particle size (≤53µm) has been investigated.

Maximum adsorption capacity, calculated from well fitted Langmuir equation, is 6.93 mg/g which increased with increase in temperature. The positive value of enthalpy change (∆H o =20.98 kJ/mol) and negative free energy change (∆G o) indicated that the adsorption of MB on clay is endothermic and involve chemical process.

Low Molecular Weight Polyethyleneimine (LMW PEI) was used for impregnation purpose. The maximum amount of LMW PEI adsorbed on activated carbon was determined to be approximately 228.2 mg/g carbon. The adsorption experiments were carried out in a batch system using potassium dichromate K2Cr2O7 as the source of Cr(VI) in the synthetic waste water and modified palm shell activated carbon as the adsorbent. The effects of pH, concentration of Cr(VI) and PEI loaded on activated carbon were studied. The adsorption data were found to fit well with the Freundlich isotherm model. This modified Palm shell activated carbon showed high adsorption capacity for chromium ions. © 2010 Elsevier Ltd.

With the increase in activated carbon loadings, the surface area, pore size and pore volume of the activated carbon loaded zeolite Y adsorbent decreased. The intensity of the diffraction patterns of zeolite Y decreased after the activated carbon was loaded. With increasing activated carbon loadings, the intensity of diffraction peaks decreased. Adsorption capacity of nitrogen (N2) was smaller than adsorption capacity of methane (CH4) by using activated carbon modified silica. When activated carbon loadings 30% wt.%, adsorption capacity of methane and nitrogen was 12.9317 wt.% and 12.6115 wt.%, these were caused by difference in molecular weight. The molecular weight of nitrogen is bigger than molecular weight of methane. © 2006 Springer. <br /> <br /><a href="http://link.springer.com/article/10.1007/s11051-005-8795-5" rel="nofollow">http://link.springer.com/article/10.1007/s11051-005-8795-5</a></div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/7966800" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="b25ce8e8dca98cb7a6c336ace8aa2b21" rel="nofollow" data-download="{"attachment_id":34437967,"asset_id":7966800,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/34437967/download_file?st=MTczMjUyMDA3Myw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="15105238" href="https://malaya.academia.edu/WanMohdAshriWanDaud">Wan Mohd Ashri Wan Daud</a><script data-card-contents-for-user="15105238" type="text/json">{"id":15105238,"first_name":"Wan Mohd Ashri","last_name":"Wan Daud","domain_name":"malaya","page_name":"WanMohdAshriWanDaud","display_name":"Wan Mohd Ashri Wan Daud","profile_url":"https://malaya.academia.edu/WanMohdAshriWanDaud?f_ri=834747","photo":"https://0.academia-photos.com/15105238/4222326/4914483/s65_wan_mohd_ashri.wan_daud.jpg"}</script></span></span></li><li class="js-paper-rank-work_7966800 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="7966800"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 7966800, container: ".js-paper-rank-work_7966800", });

Carbonization of the dried palm shells was done at 900 °C for duration of 1 h followed by steam activation at 830 °C for 30–420 min to achieve activated carbons with different degree of burn-offs. The highest micropore volume of activated carbon obtained at 53.2% burn-off was found suitable to be used as a precursor for CMS production. Subsequent benzene deposition onto activated samples at temperature range from 600 to 900 °C for various benzene concentrations have resulted in a series of CMS with different kinetic selectivities. The molecular sieving behaviour of the CMS products was assessed by kinetic adsorption isotherms of O2, N2, CO2 and CH4 at room temperature.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/1506174" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="55596d77a63bcdeb92ae01aa3bcfc303" rel="nofollow" data-download="{"attachment_id":50946264,"asset_id":1506174,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/50946264/download_file?st=MTczMjUyMDA3Myw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="1496120" href="https://usm.academia.edu/MohdAzmier">Mohd Azmier</a><script data-card-contents-for-user="1496120" type="text/json">{"id":1496120,"first_name":"Mohd","last_name":"Azmier","domain_name":"usm","page_name":"MohdAzmier","display_name":"Mohd Azmier","profile_url":"https://usm.academia.edu/MohdAzmier?f_ri=834747","photo":"https://0.academia-photos.com/1496120/531927/665537/s65_mohd.azmier.jpg"}</script></span></span></li><li class="js-paper-rank-work_1506174 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="1506174"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 1506174, container: ".js-paper-rank-work_1506174", });

The use of activated carbon as adsorbent with ethanol offers potential for low temperature cooling applications like the food retail industry. Activated carbons are commercially available in the form of powders, granules and pellets. Although powder materials have the advantage of good adsorption kinetics but they are difficult to integrate in adsorption beds. Pellets and granules come at various shapes and sizes and can be effectively accommodated in adsorption beds but offer slower kinetics compared to the powder form. <br />This work experimentally and numerically investigates the effect of pellet size on the ethanol adsorption characteristics of Norit RX3 activated carbon. Dynamic vapour sorption (DVS) testing was used for measuring the adsorption isotherms and kinetics for a range of pellet lengths ranging from 3mm to 12mm. COMSOL Multiphysics was used to simulate the adsorption effect taking into account the diffusion process. Results showed that increasing the pellet dimension in terms of diameter and length reduces the adsorption kinetics.</div></div></div><ul class="InlineList u-ph0x u-fs13"><li class="InlineList-item logged_in_only"><div class="share_on_academia_work_button"><a class="academia_share Button Button--inverseBlue Button--sm js-bookmark-button" data-academia-share="Work/12884608" data-share-source="work_strip" data-spinner="small_white_hide_contents"><i class="fa fa-plus"></i><span class="work-strip-link-text u-ml1x" data-content="button_text">Bookmark</span></a></div></li><li class="InlineList-item"><div class="download"><a id="4cafa37cde46c9eccf6a016b0ad320b6" rel="nofollow" data-download="{"attachment_id":37865447,"asset_id":12884608,"asset_type":"Work","always_allow_download":false,"track":null,"button_location":"work_strip","source":null,"hide_modal":null}" class="Button Button--sm Button--inverseGreen js-download-button prompt_button doc_download" href="https://www.academia.edu/attachments/37865447/download_file?st=MTczMjUyMDA3Myw4LjIyMi4yMDguMTQ2&s=work_strip"><i class="fa fa-arrow-circle-o-down fa-lg"></i><span class="u-textUppercase u-ml1x" data-content="button_text">Download</span></a></div></li><li class="InlineList-item"><ul class="InlineList InlineList--bordered u-ph0x"><li class="InlineList-item InlineList-item--bordered"><span class="InlineList-item-text">by <span itemscope="itemscope" itemprop="author" itemtype="https://schema.org/Person"><a class="u-tcGrayDark u-fw700" data-has-card-for-user="376570" href="https://open.academia.edu/JamesBowen">James Bowen</a><script data-card-contents-for-user="376570" type="text/json">{"id":376570,"first_name":"James","last_name":"Bowen","domain_name":"open","page_name":"JamesBowen","display_name":"James Bowen","profile_url":"https://open.academia.edu/JamesBowen?f_ri=834747","photo":"https://0.academia-photos.com/376570/97278/7827826/s65_james.bowen.jpg"}</script></span></span></li><li class="js-paper-rank-work_12884608 InlineList-item InlineList-item--bordered hidden"><span class="js-paper-rank-view hidden u-tcGrayDark" data-paper-rank-work-id="12884608"><i class="u-m1x fa fa-bar-chart"></i><strong class="js-paper-rank"></strong></span><script>$(function() { new Works.PaperRankView({ workId: 12884608, container: ".js-paper-rank-work_12884608", });

Carbonization of the dried palm shells was done at 900 °C for duration of 1 h followed by steam activation at 830 °C for 30-420 min to achieve activated carbons with different degree of burn-offs. The highest micropore volume of activated carbon obtained at 53.2% burn-off was found suitable to be used as a precursor for CMS production. Subsequent benzene deposition onto activated samples at temperature range from 600 to 900 °C for various benzene concentrations have resulted in a series of CMS with different kinetic selectivities. The molecular sieving behaviour of the CMS products was assessed by kinetic adsorption isotherms of O2, N2, CO2 and CH4 at room temperature. © 2007 Elsevier B.V.

Carbonization of the dried palm shells was done at 900 °C for duration of 1 h followed by steam activation at 830 °C for 30-420 min to achieve activated carbons with different degree of burn-offs. The highest micropore volume of activated carbon obtained at 53.2% burn-off was found suitable to be used as a precursor for CMS production. Subsequent benzene deposition onto activated samples at temperature range from 600 to 900 °C for various benzene concentrations have resulted in a series of CMS with different kinetic selectivities. The molecular sieving behaviour of the CMS products was assessed by kinetic adsorption isotherms of O2, N2, CO2 and CH4 at room temperature. © 2007 Elsevier B.V.
