Journal ArticleDOI
Biochar as a sorbent for contaminant management in soil and water: a review.
Mahtab Ahmad,Anushka Upamali Rajapaksha,Jung Eun Lim,Ming Zhang,Nanthi Bolan,Dinesh Mohan,Meththika Vithanage,Sang Soo Lee,Yong Sik Ok,Yong Sik Ok,Yong Sik Ok +10 more
TL;DR: Due to complexity of soil-water system in nature, the effectiveness of biochars on remediation of various organic/inorganic contaminants is still uncertain.
Journal ArticleDOI
Effects of pyrolysis temperature on soybean stover- and peanut shell-derived biochar properties and TCE adsorption in water.
TL;DR: Biochars developed from soybean stover and peanut shells and pyrolysis temperature influencing the BC properties was a critical factor to assess the removal efficiency of TCE from water.
Journal ArticleDOI

TL;DR: In this article, the economic feasibility of biochar application cannot be neglected and strategies for reducing biochar losses and its application costs, and increasing its use efficiency need to be developed.
Journal ArticleDOI
Trichloroethylene adsorption by pine needle biochars produced at various pyrolysis temperatures.
Mahtab Ahmad,Sang Soo Lee,Anushka Upamali Rajapaksha,Meththika Vithanage,Ming Zhang,Ju Sik Cho,Sung-Eun Lee,Yong Sik Ok,Yong Sik Ok +8 more
TL;DR: In this study, pine needles were converted to biochar (BC) at different pyrolysis temperatures of 300, 500, and 700 °C to sorb trichloroethylene (TCE), and the changes in BC properties with each temperature were evaluated, indicating prevailing sorption mechanism as pore-filling.
Journal ArticleDOI
Effects of soil dilution and amendments (mussel shell, cow bone, and biochar) on Pb availability and phytotoxicity in military shooting range soil.
TL;DR: It is found that the Pb availability in the military shooting range soil can be reduced effectively by the tested amendments or soil dilution alternately, thereby decreasing the risk of ecotoxicity.
