Journal ArticleDOI
Evaluating the Sorption Kinetics of Polychlorinated Biphenyls in Powdered and Granular Activated Carbon.
TL;DR: In this article , the authors used polymeric passive samplers to explore sorption kinetics and equilibrium for low solubility compounds as well as the differences in performance of granular and powdered forms of activated carbon for remediation of PCB contaminated sediment.
Journal ArticleDOI
Both Sides of Coin: Benefits and Potential Negative Consequences of Biochar in Sediment Remediation
TL;DR: In this paper , the potential risks of biochar were summarized and corresponding avoidance strategies for different risks were proposed, and the baseline reference and guidance implications for the biochar selection, toxicity detection, and evaluation in the field of sediment remediation were provided.
Journal ArticleDOI
Limited Effectiveness of Carbonaceous Sorbents in Sequestering Aged Organic Contaminants in Sediments
TL;DR: In this paper , three different carbonaceous sorbents, i.e., biochars, powdered activated carbon, and granular activated carbon were amended to a Superfund site marine sediment contaminated with DDT residues from decades ago.

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
Organic and inorganic contaminants removal from water with biochar, a renewable, low cost and sustainable adsorbent--a critical review.
TL;DR: A review of recent applications of biochars, produced from biomass pyrolysis (slow and fast), in water and wastewater treatment, and a few recommendations for further research have been made in the area of biochar development for application to water filtration.
Journal ArticleDOI
Application of biochar for the removal of pollutants from aqueous solutions.
TL;DR: An overview of biochar production technologies, biochar properties, and recent advances in the removal of heavy metals, organic pollutants and other inorganic pollutants using biochar is provided.

A review of biochars’ potential role in the remediation, revegetation and restoration of contaminated soils
Luke Beesley,Eduardo Moreno-Jiménez,Jose L. Gomez-Eyles,Eva Harris,Brett Robinson,Tom Sizmur +5 more
TL;DR: Specific mechanisms of contaminant-biochar retention and release over time and the environmental impact of biochar amendments on soil organisms remain somewhat unclear but must be investigated to ensure that the management of environmental pollution coincides with ecological sustainability.
Journal ArticleDOI
Octanol-water partition coefficients of polychlorinated biphenyl congeners
TL;DR: In this paper, the total surface area (TSA) for polychlorinated biphenyl (PCB) congeners was determined by assuming planar molecules, van der Waal's radii for component atoms, and appropriate values for solvent radius, bond angles, and distances.
