Commercially available multi-walled carbon nanotube (MWCNT) and biochar pyrolyzed from soybean stover at 300 °C (BC) at 0.5, 1 and 2.5% (w w-1) were used to remediate the contaminated soil in an incubation experiment. Both DTPA (bioavailable) and TCLP (leaching) extraction procedures were used to compare the metal/loid availability and leaching by the amendments in soil. The addition of BC was more effective in immobilizing mobile Pb and Cu in the soil than that in MWCNT. The BC reduced the concentrations of Pb and Cu in the soil by 17.6 and 16.2%, respectively. However, both MWCNTs and BC increased Sb bioavailability by 1.4-fold and 1.6-fold, respectively, in DTPA extraction , compared to the control. The toxicity characteristic leaching procedure (TCLP) test showed that the leachability of Pb in the soil amended with 2.5% MWCNT was 1.3-fold higher than that the una-mended soil, whereas the BC at 2.5% decreased the TCLP-extractable Pb by 19.2%. Precipitation and adsorption via electrostatic and p–p electron donor– acceptor interactions were postulated to be involved in the interactions of Pb and Cu with surfaces of the BC in the amended soils, whereas ion exchange mechanisms might be involved in the immobiliza-tion of Cu in the MWCNT-amended soils. The application of BC derived from soybean stover can be a low-cost technology for simultaneously immobilizing bioavailable Pb and Cu in the shooting range soils; however, neither of amendments was effective in Sb immobilization.","author":[{"@context":"https://schema.org","@type":"Person","name":"Anushka Upamali

Commercially available multi-walled carbon nanotube (MWCNT) and biochar pyrolyzed from soybean stover at 300 °C (BC) at 0.5, 1 and 2.5% (w w-1) were used to remediate the contaminated soil in an incubation experiment. Both DTPA (bioavailable) and TCLP (leaching) extraction procedures were used to compare the metal/loid availability and leaching by the amendments in soil. The addition of BC was more effective in immobilizing mobile Pb and Cu in the soil than that in MWCNT. The BC reduced the concentrations of Pb and Cu in the soil by 17.6 and 16.2%, respectively. However, both MWCNTs and BC increased Sb bioavailability by 1.4-fold and 1.6-fold, respectively, in DTPA extraction , compared to the control. The toxicity characteristic leaching procedure (TCLP) test showed that the leachability of Pb in the soil amended with 2.5% MWCNT was 1.3-fold higher than that the una-mended soil, whereas the BC at 2.5% decreased the TCLP-extractable Pb by 19.2%. Precipitation and adsorption via electrostatic and p–p electron donor– acceptor interactions were postulated to be involved in the interactions of Pb and Cu with surfaces of the BC in the amended soils, whereas ion exchange mechanisms might be involved in the immobiliza-tion of Cu in the MWCNT-amended soils.

In the present study, BCR, TCLP, CaCl2, and SBET techniques were employed to evaluate the simultaneous effectiveness of rice straw (RS) and its derived biochar (BC), multiwall carbon nanotube (MWCNT), and single superphosphate (SSP) to immobilize the Pb and Cu in co-contaminated soil. The BCR sequential extraction results suggested that with increasing BC and SSP amount, the acid-soluble fractions decreased while oxidizable and residual proportions of Pb and Cu were increased significantly. Compared to SSP, the application of BC amendment substantially modified partitioning of Cu from easily exchangeable phase to less bioavailable residual bound fraction. The immobilized Pb and Cu were mainly transformed to reducible forms. The TCLP and CaCl2-extracted Pb and Cu were reduced significantly by the addition of BC compared to RS and MWCNT, where...</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Immobilization of Pb and Cu in polluted soil by superphosphate, multi-walled carbon nanotube, rice straw and its derived biochar","attachmentId":90963539,"attachmentType":"pdf","work_url":"https://www.academia.edu/86533503/Immobilization_of_Pb_and_Cu_in_polluted_soil_by_superphosphate_multi_walled_carbon_nanotube_rice_straw_and_its_derived_biochar","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/86533503/Immobilization_of_Pb_and_Cu_in_polluted_soil_by_superphosphate_multi_walled_carbon_nanotube_rice_straw_and_its_derived_biochar"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="1" data-entity-id="38049848" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/38049848/Influence_of_bioenergy_waste_biochar_on_proton_and_ligand_promoted_release_of_Pb_and_Cu_in_a_shooting_range_soil">Influence of bioenergy waste biochar on proton-and ligand-promoted release of Pb and Cu in a shooting range soil</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="60911154" href="https://usq.academia.edu/PrasannaKumarathilaka">Prasanna Kumarathilaka</a><span>, </span><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="29875" href="https://king-saud.academia.edu/MohammadAlwabel">Mohammad Alwabel</a></div><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Influence of bioenergy waste biochar on proton-and ligand-promoted release of Pb and Cu in a shooting range soil","attachmentId":58074554,"attachmentType":"pdf","work_url":"https://www.academia.edu/38049848/Influence_of_bioenergy_waste_biochar_on_proton_and_ligand_promoted_release_of_Pb_and_Cu_in_a_shooting_range_soil","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/38049848/Influence_of_bioenergy_waste_biochar_on_proton_and_ligand_promoted_release_of_Pb_and_Cu_in_a_shooting_range_soil"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="2" data-entity-id="105255738" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/105255738/The_Use_of_biochar_in_the_Remediation_of_Pb_Cd_and_Cu_Contaminated_Soils_The_Impact_of_biochar_Feedstock_and_Preparation_Conditions_on_Its_Remediation_Capacity">The Use of biochar in the Remediation of Pb, Cd, and Cu-Contaminated Soils.

During the last decades, several methods have been developed aiming at its remediation, including the use of biochar as a soil amendment. In the present work, we have assessed the reduction of Pb, Cd, and Cu soil concentrations as a function of the mixing ratio of biochar added to soil, as well as the source of biochar employed. Furthermore, we have investigated the effects of biochar addition relating to the chemical forms of heavy metals (HMs) related to their bioavailability and mobility. The concentrations of HMs were determined by the BCR (European Community Bureau of Reference) sequential extraction procedure before and after biochar addition to the soils. Five types of biochar were used, obtained as by-products of sugarcane bagasse (Β), bamboo (ΒΒ), rice straw (RSB), garden waste (GB), and paulownia (PB) treatment, respectively.

A large number of shooting ranges is present in Egypt without paying attention to controlling the environmental pollution. The main objective of this research was to investigate the integrated effect of applying biochar (BC) derived from sugar cane wastes for soil fertility improvement and lead (Pb) stabilization. To achieve this goal, sugar cane wastes were collected, and used for producing the BC. A small-scale BC production unit was designed by using double metal barrels; thereafter, sugar cane wastes were placed and burned inside the BC producing unit. The produced BC was used to restore the biological function of a polluted shooting range soil by immobilizing Pb and improving the soil fertility. A surface sandy loam soil was collected from a shooting range site in the Giza Governorate-Egypt and was incubated for 365 days with different application levels (0.0, 1.0, 2.5, 5.0, 10.0, 20.0 and 30.0% w/w) of BC. The results showed that the addition of BC significantly increased the soil water holding capacity, available nutrients (N and P) and cation exchange capacity as well as stimulated the microbial growth (bacteria and fungi) in the soil. Moreover, the addition of BC led to a significant decrease in the available Pb fraction by 97.0%, as compared to the untreated soil. The phytotoxicity test revealed that the addition of BC significantly increased maize biomass (shoots and roots), especially with applications of 3% and 5% treatments. However, no plant growth occurred on the untreated soil. Furthermore, Pb uptake by maize plants significantly decreased with increasing the level of applied BC. Our findings provide evidence that BC application decreased Pb toxicity by immobilizing Pb and improving soil quality. Therefore, BC can be effectively used for sustainable development and environmental protection.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"BIOCHAR: A SOLUTION FOR SOIL LEAD (Pb) POLLUTION","attachmentId":55516937,"attachmentType":"pdf","work_url":"https://www.academia.edu/35647434/BIOCHAR_A_SOLUTION_FOR_SOIL_LEAD_Pb_POLLUTION","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/35647434/BIOCHAR_A_SOLUTION_FOR_SOIL_LEAD_Pb_POLLUTION"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="6" data-entity-id="31764523" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/31764523/Lead_and_copper_immobilization_in_a_shooting_range_soil_using_soybean_stover_and_pine_needle_derived_biochars_Chemical_microbial_and_spectroscopic_assessments">Lead and copper immobilization in a shooting range soil using soybean stover- and pine needle-derived biochars: Chemical, microbial and spectroscopic assessments</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="12542231" href="https://sjp.academia.edu/AnushkaUpamaliRajapaksha">Anushka Upamali Rajapaksha</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Journal of Hazardous Materials, 2015</p><p class="ds-related-work--abstract ds2-5-body-sm">Biochar (BC) could be a potential candidate for the remediation of metal contaminated soil. Mechanistic understandings are needed for the appropriate selection of BC and investigating molecular microbial ecological interactions. The soybean stover-derived BCs were more effective in immobilizing Pb (88%) and Cu (87%) than the pine needle-derived BCs in a contaminated shooting range soil. The sequential chemical extractions indicated that BCs stimulated the geochemical transformation of metal species. Spectroscopic investigations using scanning electron microscopic elemental dot mapping and extended X-ray absorption fine structure spectroscopic measurements showed that Pb in the BCs amended soils was immobilized by the formation of stable chloropyromorphite. Soil organic C and microbial activity were also enhanced by BC. The non-labile C fraction in the soil amended with BCs produced at 700°C was increased. Biochars showed less impact on the bacterial community than feedstock biomass as promulgated by the pyrosequencing of 16S rRNA gene. The feedstock type (namely soybean stover and pine needles) was the main factor influencing the BCs efficacy on metals&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;
