Biochar for the removal of contaminants from soil and water: a review

Biochar, Journal Year: 2022, Volume and Issue: 4(1)

Published: March 15, 2022

Abstract Biochar shows significant potential to serve as a globally applicable material remediate water and soil owing the extensive availability of feedstocks conducive physio-chemical surface characteristics. This review aims highlight biochar production technologies, characteristics biochar, latest advancements in immobilizing eliminating heavy metal ions organic pollutants water. Pyrolysis temperature, heat transfer rate, residence time, type feedstock are critical influential parameters. Biochar’s efficacy managing contaminants relies on pore size distribution, groups, ion-exchange capacity. The molecular composition physical architecture may be crucial when practically applied soil. In general, produced at relatively high pyrolysis temperatures can effectively manage via increasing area, hydrophobicity microporosity. generated lower is deemed more suitable for removing polar inorganic through oxygen-containing functional precipitation electrostatic attraction. also presents existing obstacles future research direction related biochar-based materials effluents Graphical

Heterogeneous Photocatalytic Activation of Persulfate for the Removal of Organic Contaminants in Water: A Critical Review

ACS ES&T Engineering, Journal Year: 2022, Volume and Issue: 2(4), P. 527 - 546

Published: March 8, 2022

Heterogeneous photocatalytic persulfate (PS) activation technologies are being intensively studied for water treatment due to their friendly environmental benefits and photosynergistic effect in comparison with traditional PS systems. Previous reviews have summarized diverse methods the role of light systems, but it is still urgent provide a comprehensive review on deep understanding rational design heterogeneous PS-based advanced oxidation processes (AOPs). This intends thoroughly address in-depth fundamentals mechanisms PS-AOPs. Challenges improvement strategies PS-AOPs also critically discussed. On basis detailed survey published studies, PS-AOPs, including Fe-based, TiO2-based, other metal based, bimetallic, metal-free carefully clarified. Finally, engineering implications prospects enumerated developing efficient environmentally treatment. It expected that this will motivate researchers construct novel promising
