nanocarbon particles with a quoted specific surface area of 100, 500, 1000 and 1400 m2/g, respectively, were used to investigate the influence of specific surface areas of activated nanocarbon on ultra drawing and ultimate tensile properties of ultrahigh molecular weight polyethylene (UHMWPE), UHMWPE/activated nanocarbon and UHMWPE/ functionalized activated nanocarbon fibers. The specific surface areas of well dispersed functionalized activated nanocarbon in UHMWPE/functionalized activated nanocarbon fibers can positively affect their ultra drawing, orientation, ultimate tensile properties and “micro-fibril” characteristics. Excellent orientation and ultimate tensile properties of UHMWPE/nanofiller fibers can be prepared by ultra drawing the UHMWPE/functionalized activated nanocarbon as-prepared fibers with optimal contents and compositions of functionalized activated nanocarbon. The ultimate tensile strength value of the best prepared UHMWPE/functionalized activated nanocarbon drawn fiber reached 8.0 GPa, which was about 2.86 times of that of the best-prepared UHMWPE drawn fiber prepared in this study. Specific surface area, morphological and Fourier transform infrared analyses of original and functionalized activated nanocarbon and/or investigations of thermal, orientation factor and ultimate tensile properties of as-prepared and/or drawn UHMWPE/functionalized activated nanocarbon fibers were performed to understand the above-improved ultra drawing and ultimate tensile properties of the UHMWPE/functionalized activated nanocarbon fibers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activated%20nanocarbon" title="activated nanocarbon">activated nanocarbon</a>, <a href="https://publications.waset.org/abstracts/search?q=specific%20surface%20areas" title=" specific surface areas"> specific surface areas</a>, <a href="https://publications.waset.org/abstracts/search?q=ultradrawing" title=" ultradrawing"> ultradrawing</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrahigh%20molecular%20weight%20polyethylene" title=" ultrahigh molecular weight polyethylene"> ultrahigh molecular weight polyethylene</a> </p> <a href="https://publications.waset.org/abstracts/56276/ultradrawing-and-ultimate-tensile-properties-of-ultrahigh-molecular-weight-polyethylene-composite-fibers-filled-with-activated-nanocarbon-particles-with-varying-specific-surface-areas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56276.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">372</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">781</span> Efficiency of Modified Granular Activated Carbon Coupled with Membrane Bioreactor for Trace Organic Contaminants Removal</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mousaab%20Alrhmoun">Mousaab Alrhmoun</a>, <a href="https://publications.waset.org/abstracts/search?q=Magali%20Casellas"> Magali Casellas</a>, <a href="https://publications.waset.org/abstracts/search?q=Michel%20Baudu"> Michel Baudu</a>, <a href="https://publications.waset.org/abstracts/search?q=Christophe%20Dagot"> Christophe Dagot </a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the study is to improve removal of trace organic contaminants dissolved in activated sludge by the process of filtration with membrane bioreactor combined with modified activated carbon, for a maximum removal of organic compounds characterized by low molecular weight.

However, commercially activated carbons generally require complicated processes and high production costs. Therefore, in this study, an activated carbon originating from green coke waste, that is economically affordable will be used as a carbon source. To synthesize activated carbon, KOH as an activator was employed with variation of C:KOH in ratio of 1:2, 1:3, 1:4, and 1:5, respectively, with an activation temperature of 700°C. The characterizations of activated carbon are obtained from Scanning Electron Microscopy, Energy Dispersive X-Ray, Raman Spectroscopy, and Brunauer-Emmett-Teller. The optimal activated carbon sample with specific surface area of 2,024 m²/g with high carbon content ( > 80%) supported by the high porosity carbon image obtained by SEM was prepared at C:KOH ratio of 1:4. The result shows that the synthesized activated carbon would be an ideal choice for energy storage device applications. Therefore, this study is expected to reduce the costs of activated carbon production by expanding the utilization of petroleum waste. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon" title="activated carbon">activated carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20storage%20material" title=" energy storage material"> energy storage material</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20coke" title=" green coke"> green coke</a>, <a href="https://publications.waset.org/abstracts/search?q=specific%20surface%20area" title=" specific surface area"> specific surface area</a> </p> <a href="https://publications.waset.org/abstracts/126533/synthesis-and-characterization-of-green-coke-derived-activated-carbon-by-koh-activation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126533.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">167</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">779</span> Adsorption of Chromium Ions from Aqueous Solution by Carbon Adsorbent</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Heydari">S.

Activated carbon adsorption has proven to be an effective process for the removal of trace metal contaminants from aqueous media. This paper was investigated chromium adsorption efficiency by commercial activated carbon. The sorption studied as a function of activated carbon particle size, dose of activated carbon and initial pH of solution. Adsorption tests for the effects of these factors were designed with Taguchi approach. According to the Taguchi parameter design methodology, L9 orthogonal array was used. Analysis of experimental results showed that the most influential factor was initial pH of solution. The optimum conditions for chromium adsorption by activated carbons were found to be as follows: Initial feed pH 6, adsorbent particle size 0.412 mm and activated carbon dose 6 g/l. Under these conditions, nearly %100 of chromium ions was adsorbed by activated carbon after 2 hours. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chromium" title="chromium">chromium</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption" title=" adsorption"> adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=Taguchi%20method" title=" Taguchi method"> Taguchi method</a>, <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon" title=" activated carbon"> activated carbon</a> </p> <a href="https://publications.waset.org/abstracts/3442/adsorption-of-chromium-ions-from-aqueous-solution-by-carbon-adsorbent" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3442.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">400</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">778</span> Activated Carbons Prepared from Date Pits for Hydrogen Storage </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Belhachemi">M.

The hydrogen adsorption experiments were carried at 298K in the 0–100 bar pressure range using a volumetric equipment.

Indeed, the activated carbon has promising physicochemical properties desired for a considerable number of applications. In this regard, we are proposing an enhanced and green technology for increasing the efficiency and performance of the activated carbon to various applications. The technique poses on the use of natural extracts from tuberous and cereals based-solutions. These solutions showed high potentiality to be used in the synthesis of activated carbon-graphene composite with only 3 mL. The extracted liquid from tuberous sourcing was enough to induce precipitation within a fraction of a minute in contrast to that from cereal sourced. Using these extracts, a synthesis of activated carbon-graphene composite was successful. Different characterization techniques such as XRD, SEM, FTIR, BET, and Raman spectroscopy were performed to investigate the composite materials. The results confirmed a conjugation between activated carbon and graphene material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon" title="activated carbon">activated carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=cereals" title=" cereals"> cereals</a>, <a href="https://publications.waset.org/abstracts/search?q=extract%20solution" title=" extract solution"> extract solution</a>, <a href="https://publications.waset.org/abstracts/search?q=graphene" title=" graphene"> graphene</a>, <a href="https://publications.waset.org/abstracts/search?q=tuberous" title=" tuberous"> tuberous</a> </p> <a href="https://publications.waset.org/abstracts/132585/viable-use-of-natural-extract-solutions-from-tuberous-and-cereals-to-enhance-the-synthesis-of-activated-carbon-graphene-composite" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132585.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">146</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">776</span> Preparation and Characterization of Activated Carbon from Animal Bone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Getenet%20Aseged%20Zeleke">Getenet Aseged Zeleke</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this project was to study the synthesis of activated carbon from low-cost animal beef and the characterization of the product obtained.

High surface area of activated carbon is due to the porous structure. Activated carbon, using a variety of materials such as coal and cellulosic materials; can be obtained by both physical and chemical methods. The prepared activated carbon can be used for decolorize, deodorize and also can be used for removal of organic and non-organic pollution. In this study, pomegranate peel was subjected to 800W microwave power for 1 to 4 minutes. Also fresh pomegranate peel was used for the reference material. Then ZnCl2 was used for the chemical activation purpose. After the activation process, activated pomegranate peels were used for the adsorption of Zn metal (40 ppm) in the waste water.

In the present study, the characteristic features of an efficient activated carbon (AC) synthesized from Indian gooseberry seed shells for the copper (II) adsorption are reported. A three-step chemical activation method consisting of the impregnation, carbonization and subsequent activation is used to produce the activated carbon. The copper adsorption kinetics and isotherms onto the activated carbon were analyzed. As per present investigation, Indian gooseberry seed shells showed the BET surface area of 1359 m²/g. The maximum adsorptivity of the activated carbon at a pH value of 9.52 was found to be 44.84 mg/g at 30°C. The adsorption process followed the pseudo-second-order kinetic model along with the Langmuir adsorption isotherm. This AC could be used as a favorable and cost-effective copper (II) adsorbent in wastewater treatment to remove the metal contaminants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon" title="activated carbon">activated carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption%20isotherm" title=" adsorption isotherm"> adsorption isotherm</a>, <a href="https://publications.waset.org/abstracts/search?q=kinetic%20model" title=" kinetic model"> kinetic model</a>, <a href="https://publications.waset.org/abstracts/search?q=characterization" title=" characterization"> characterization</a> </p> <a href="https://publications.waset.org/abstracts/100344/an-efficient-activated-carbon-for-copper-ii-adsorption-synthesized-from-indian-gooseberry-seed-shells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/100344.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">161</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">773</span> Emergency Treatment of Methanol Poisoning: A Mathematical Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Priyanka%20Ghosh">Priyanka Ghosh</a>, <a href="https://publications.waset.org/abstracts/search?q=Priti%20Kumar%20Roy"> Priti Kumar Roy</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Every year a considerable number of people die due to methyl alcohol poisoning, in which most of them die even before proper treatment.

According to the Nitrogen adsorption isotherms, the micropore and mesopore are both developed in the activated carbon. The specific surface area and the mesopore volume fractions of the activated carbon increased with the raise of activation temperature.

The effect of the production variables such as impregnation chemical agents, impregnation ratio, activation temperature and activation time were investigated. Carbon obtained using the optimum conditions (CaCl2/ 1:1/ 500°C/2H) was characterized by various analytical techniques scanning electron microscopy (SEM), infrared spectroscopic analysis (FTIR) and zero-point-of-charge (pHpzc). Adsorption tests of methylene blue on the optimal activated carbon were conducted. The effects of contact time, amount of adsorbent, initial dye concentration and pH were studied. The adsorption equilibrium examined using Langmuir, Freundlich, Temkin and Redlich–Peterson models reveals that the Langmuir model is most appropriate to describe the adsorption process. The kinetics of MB sorption onto activated carbon follows the pseudo-second order rate expression. The examination of the thermodynamic analysis indicates that the adsorption process is spontaneous (ΔG ° < 0) and endothermic (ΔH ° > 0), the positive value of the standard entropy shows the affinity between the activated carbon and the dye. The present study showed that the produced optimal activated carbon prepared from Algerian alfa is an effective low-cost adsorbent and can be employed as alternative to commercial activated carbon for removal of MB dye from aqueous solution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon" title="activated carbon">activated carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption" title=" adsorption"> adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=cationic%20dyes" title=" cationic dyes"> cationic dyes</a>, <a href="https://publications.waset.org/abstracts/search?q=Algerian%20alfa" title=" Algerian alfa"> Algerian alfa</a> </p> <a href="https://publications.waset.org/abstracts/49655/preparation-of-activated-carbon-from-lignocellulosic-precursor-for-dyes-adsorption" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49655.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">228</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">766</span> In-Situ LDH Formation of Sodium Aluminate Activated Slag</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tao%20Liu">Tao Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Qingliang%20Yu"> Qingliang Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=H.%20J.%20H.%20Brouwers"> H.

The characterisation results showed this biosorbent had very high specific surface area and functional groups. The adsorption equilibrium data was well described by Langmuir, whilst kinetics data by pseudo-first order, pseudo-second order and Intraparticle diffusion models. The adsorption process could be described by the pseudo-second order kinetic. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coconut%20shell" title="coconut shell">coconut shell</a>, <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon" title=" activated carbon"> activated carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=adsorption%20isotherm%20and%20kinetics" title=" adsorption isotherm and kinetics"> adsorption isotherm and kinetics</a>, <a href="https://publications.waset.org/abstracts/search?q=lead%20removal" title=" lead removal"> lead removal</a> </p> <a href="https://publications.waset.org/abstracts/38679/adsorption-studies-of-lead-from-aqueos-solutions-on-cocount-shell-activated-carbon" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38679.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">308</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">763</span> Greywater Treatment Using Activated Biochar Produced from Agricultural Waste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pascal%20Mwenge">Pascal Mwenge</a>, <a href="https://publications.waset.org/abstracts/search?q=Tumisang%20Seodigeng"> Tumisang Seodigeng</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The increase in urbanisation in South Africa has led to an increase in water demand and a decline in freshwater supply. Despite this, poor water usage is still a major challenge in South Africa, for instance, freshwater is still used for non-drinking applications. The freshwater shortage can be alleviated by using other sources of water for non-portable purposes such as greywater treated with activated biochar produced from agricultural waste. The success of activated biochar produced from agricultural waste to treat greywater can be both economically and environmentally beneficial. Greywater treated with activated biochar produced from agricultural waste is considered a cost-effective wastewater treatment.  This work was aimed at determining the ability of activated biochar to remove Total Suspended Solids (TSS), Ammonium (NH<sub>4</sub>-N), Nitrate (NO<sub>3</sub>-N), and Chemical Oxygen Demand (COD) from greywater. The experiments were carried out in 800 ml laboratory plastic cylinders used as filter columns. 2.5 cm layer of gravel was used at the bottom and top of the column to sandwich the activated biochar material. Activated biochar (200 g and 400 g) was loaded in a column and used as a filter medium for greywater. Samples were collected after a week and sent for analysis. Four types of greywater were treated: Kitchen, floor cleaning water, shower and laundry water. The findings showed: 95% removal of TSS, 76% of NO<sub>3</sub>-N and 63% of COD on kitchen greywater and 85% removal of NH<sub>4</sub>-N on bathroom greywater, as highest removal of efficiency of the studied pollutants. The results showed that activated biochar produced from agricultural waste reduces a certain amount of pollutants from greywater. The results also indicated the ability of activated biochar to treat greywater for onsite non-potable reuse purposes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activated%20biochar%20produced%20from%20agriculture%20waste" title="activated biochar produced from agriculture waste">activated biochar produced from agriculture waste</a>, <a href="https://publications.waset.org/abstracts/search?q=ammonium" title=" ammonium"> ammonium</a>, <a href="https://publications.waset.org/abstracts/search?q=NH%E2%82%84-N" title=" NH₄-N"> NH₄-N</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20oxygen%20demand" title=" chemical oxygen demand"> chemical oxygen demand</a>, <a href="https://publications.waset.org/abstracts/search?q=COD" title=" COD"> COD</a>, <a href="https://publications.waset.org/abstracts/search?q=greywater" title=" greywater"> greywater</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrate" title=" nitrate"> nitrate</a>, <a href="https://publications.waset.org/abstracts/search?q=NO%E2%82%83-N" title=" NO₃-N"> NO₃-N</a>, <a href="https://publications.waset.org/abstracts/search?q=total%20suspended%20solids" title=" total suspended solids"> total suspended solids</a>, <a href="https://publications.waset.org/abstracts/search?q=TSS" title=" TSS"> TSS</a> </p> <a href="https://publications.waset.org/abstracts/95193/greywater-treatment-using-activated-biochar-produced-from-agricultural-waste" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95193.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">203</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">762</span> Thermal Regeneration of CO2 Spent Palm Shell-Polyetheretherketone Activated Carbon Sorbents </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Usman%20D.%20Hamza">Usman D.

The adsorption/desorption process was carried out using static volumetric adsorption. Regeneration is important in the overall economy of the process and waste minimization. This work focuses on the thermal regeneration of the CO2 exhausted microwave activated carbons. The regeneration strategy adopted was thermal with nitrogen purge desorption with N2 feed flow rate of 20 ml/min for 1 h at atmospheric pressure followed by drying at 1500C. Seven successive adsorption/regeneration processes were carried out on the material. It was found that after seven adsorption regeneration cycles; the regeneration efficiency (RE) for CO2 activated carbon from palm shell only (M4P0) was more than 90% while that of hybrid palm shell-PEEK (M4P2, M5P2) was above 95%. The cyclic adsorption and regeneration shows the stability of the adsorbent materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon" title="activated carbon">activated carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=palm%20shell-PEEK" title=" palm shell-PEEK"> palm shell-PEEK</a>, <a href="https://publications.waset.org/abstracts/search?q=regeneration" title=" regeneration"> regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal" title=" thermal"> thermal</a> </p> <a href="https://publications.waset.org/abstracts/25253/thermal-regeneration-of-co2-spent-palm-shell-polyetheretherketone-activated-carbon-sorbents" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25253.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">488</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">761</span> Removal of Chromium (VI) from Aqueous Solution by Teff (Eragrostis Teff) Husk Activated Carbon: Optimization, Kinetics, Isotherm, and Practical Adaptation Study Using Response Surface Methodology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tsegaye%20Adane%20Birhan">Tsegaye Adane Birhan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, rapid industrialization has led to the excessive release of heavy metals such as Cr (VI) into the environment. Exposure to chromium (VI) can cause kidney and liver damage, depressed immune systems, and a variety of cancers. Therefore, treatment of Cr (VI) containing wastewater is mandatory. This study aims to optimize the removal of Cr (VI) from an aqueous solution using locally available Teff husk-activated carbon adsorbent. The laboratory-based study was conducted on the optimization of Cr (VI) removal efficiency of Teff husk-activated carbon from aqueous solution. A central composite design was used to examine the effect of the interaction of process parameters and to optimize the process using Design Expert version 7.0 software. The optimized removal efficiency of Teff husk activated carbon (95.597%) was achieved at 1.92 pH, 87.83mg/L initial concentration, 20.22g/L adsorbent dose and 2.07Hrs contact time. The adsorption of Cr (VI) on Teff husk-activated carbon was found to be best fitted with pseudo-second-order kinetics and Langmuir isotherm model of the adsorption. Teff husk-activated carbon can be used as an efficient adsorbent for the removal of chromium (VI) from contaminated water. Column adsorption needs to be studied in the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=batch%20adsorption" title="batch adsorption">batch adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=chromium%20%28VI%29" title=" chromium (VI)"> chromium (VI)</a>, <a href="https://publications.waset.org/abstracts/search?q=teff%20husk%20activated%20carbon" title=" teff husk activated carbon"> teff husk activated carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=response%20surface%20methodology" title=" response surface methodology"> response surface methodology</a>, <a href="https://publications.waset.org/abstracts/search?q=tannery%20wastewater" title=" tannery wastewater"> tannery wastewater</a> </p> <a href="https://publications.waset.org/abstracts/194677/removal-of-chromium-vi-from-aqueous-solution-by-teff-eragrostis-teff-husk-activated-carbon-optimization-kinetics-isotherm-and-practical-adaptation-study-using-response-surface-methodology" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194677.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">8</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">760</span> Valorization of Argan Residuals for the Treatment of Industrial Effluents</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salim%20Ahmed">Salim Ahmed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of this study was to recover a natural residue in the form of activated carbon prepared from Moroccan "argan pits and date pits" plant waste.

The MWCNT-PDMS CPE was initially activated via potentiodynamic cycling in a basic (NaOH) solution, which resulted in enhanced electrochemical properties. Electrochemical Impedance Spectroscopy measurements revealed a significantly lower charge transfer resistance (Rct) for the OH--activated MWCNT-PDMS CPE (Rct = 5.08kΩ) as compared to buffer (pH 7)-activated MWCNT-PDMS CPE (Rct = 25.9kΩ). Reversibility analysis of Fe(CN)63-/4- redox couple of both Buffer-Activated CPE and OH--Activated CPE showed that the OH—Activated CPE have peak current ratio (Ia/Ic) of 1.11 at 100mV/s while 2.12 for the Buffer-Activated CPE; this showed an electrochemically reversible behavior for Fe(CN)63-/4- redox couple even at relatively fast scan rate using the OH--activated CPE. Enhanced voltammetric signal for DA and significant peak separation between DA and UA was obtained using the OH--activated MWCNT-PDMS CPE in the presence of 50 μM AA via Differential Pulse Voltammetry technique. The anodic peak currents which appeared at 0.263V and 0.414 V were linearly increasing with increasing concentrations of DA and UA, respectively. The linear ranges were obtained at 25 μM – 100 μM for both DA and UA. The detection limit was determined to be 3.86 μM for DA and 5.61 μM for UA.

This raises the need for the development of processes that are cheaper. Activated biocarbon was used in batch and filtration system to remove nitrates and phosphates.

It is very difficult to treat dyeing wastewater by conventional methods. Here an attempt has been made to treat dyeing wastewater by the conventional and advanced method for removal of COD. Fenton process is the advanced method and activated carbon treatment is the conventional method. Experiments have been done on synthetic wastewater prepared from three different dyes; acidic, disperse and reactive. Experiments have also been conducted on real effluent obtained from industry. The optimum dose of catalyst and hydrogen peroxide in Fenton process and optimum activated carbon dose for each of these wastewaters were obtained. In Fenton treatment, COD removal was obtained up to 95% whereas 70% removal was obtained with activated carbon treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon" title="activated carbon">activated carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=advanced%20oxidation%20process" title=" advanced oxidation process"> advanced oxidation process</a>, <a href="https://publications.waset.org/abstracts/search?q=dyeing%20waste%20water" title=" dyeing waste water"> dyeing waste water</a>, <a href="https://publications.waset.org/abstracts/search?q=fenton%20oxidation%20process" title=" fenton oxidation process"> fenton oxidation process</a> </p> <a href="https://publications.waset.org/abstracts/81307/comparative-study-of-fenton-and-activated-carbon-treatment-for-dyeing-waste-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81307.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">211</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">754</span> Evaluation of the Adsorption Adaptability of Activated Carbon Using Dispersion Force</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masao%20Fujisawa">Masao Fujisawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Hirohito%20Ikeda"> Hirohito Ikeda</a>, <a href="https://publications.waset.org/abstracts/search?q=Tomonori%20Ohata"> Tomonori Ohata</a>, <a href="https://publications.waset.org/abstracts/search?q=Miho%20Yukawa"> Miho Yukawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Hatsumi%20Aki"> Hatsumi Aki</a>, <a href="https://publications.waset.org/abstracts/search?q=Takayoshi%20Kimura"> Takayoshi Kimura</a> </p> <p class="card-text"><strong>Abstract:</strong></p> We attempted to predict adsorption coefficients by utilizing dispersion energies.

Douadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The current work has a goal of the preparation of activated carbon from the stones of dates from southern Algeria (El-Oued province) using a simple pyrolysis proceeded by chemical impregnation in sulphuric acid. For the preparation of the carbon, we choose the diameter of the pellets (0.5-1)mm, activation by acid and water (1:1), carbonization at 450˚C. The prepared carbon has the following characteristics: specific surface 125.86 m2/g, methylene blue number 40, CCE = 0.3meq.g/l, IR and micrographics SEM. The activated carbon thus obtained is used at the water purification in wastewater treatment plant (WWTP) at Kouinine, El- Oued province, to totally eliminate phosphorus. We analyzed the water at the WWTP before the purification procedure. In this study, we have looked at the effect of the following parameters on the adsorption of carbon: the pH, the contact time (Tc) and the agitation speed (Va). The best conditions for phosphorus adsorption are: pH=4 or pH >5, Tc = 60 min and Va = 900 rotations per minute. <p class="card-text"><strong>Keywords:</strong> <a
