Adsorption kinetic modeling using pseudo-first order and pseudo-second order rate laws: A review

Cleaner Engineering and Technology, Journal Year: 2020, Volume and Issue: 1, P. 100032 - 100032

Published: Dec. 1, 2020

Adsorption for water and wastewater treatment has been the subject of many research in scientific community, focusing mainly on either equilibrium or kinetic studies. kinetics are commonly modeled using pseudo-first pseudo-second order rate laws. Analyses published works past two decades indicated that is considered to be superior model as it can represent adsorption systems. However, critical assessment modeling techniques practices suggests its superiority could a consequence currently acceptable norms which tend favor model. The partiality was due several pitfalls often neglected. In addition, used validation tools haphazardly redundantly. As such, they cannot sufficiently provide any kind certainty validity To eliminate biasness, new method proposed then employed re-examine previously data.

New trends in biochar pyrolysis and modification strategies: feedstock, pyrolysis conditions, sustainability concerns and implications for soil amendment

Soil Use and Management, Journal Year: 2020, Volume and Issue: 36(3), P. 358 - 386

Published: April 11, 2020

Abstract As a waste‐derived soil amendment with long history, biochar has received extensive attention for its capability to improve fertility/health; remove or immobilize contaminants in soil, water and air; mitigate climate change. With the aim of producing engineered biochars excellent performances, new trends pyrolytic production modification strategies have emerged. This review critically summarizes novel pyrolysis methods (e.g., microwave‐assisted pyrolysis, co‐pyrolysis wet pyrolysis) approaches mineral modification, photocatalytic electrochemical modification) focus on (a) mechanisms involved environmental remediation processes including immobilization, contaminant adsorption catalytic oxidation; (b) effects feedstock conditions physicochemical properties; (c) sustainability considerations strategies; (d) feasibility extrapolating results from wastewater treatment remediation. It is argued that order achieve maximum net benefits, ‘greener’ are warranted, risks associated contaminated sorption can be minimized through various co‐pyrolysis). Furthermore, combined emerging synthesize more ‘effective’ biochars. Considering similar aims increase surface area, introduce oxygen‐containing functional groups, aromaticity), applicability several could future expanded adsorption/degradation aqueous media remediation/fertility improvement.

Chemical and biological immobilization mechanisms of potentially toxic elements in biochar-amended soils

Critical Reviews in Environmental Science and Technology, Journal Year: 2019, Volume and Issue: 50(9), P. 903 - 978

Published: Aug. 6, 2019

The application of biochars for the remediation water and soils contaminated with potentially toxic elements (PTEs) has seen a recent growing interest. mechanisms chemical immobilization PTEs in aqueous media have been well defined. However, by which interact soil matrix are more complex. biological their interactions biochar-amended not as This review presents an overview factors governing synergistic effect microorganisms processes. effectiveness improvement microbial mainly depends on biochar properties, rates, environments such organic matter content, clay type pH redox potential. Although some modified appear to be better than pristine PTEs, potential adverse impacts activity should considered. highlights most common analytical methods discover molecular interaction between future research areas required understanding biochar-PTE polluted systems.
