Catalytic ozonation relies on the direct oxidation by ozone (O3) and indirect reactive oxygen species (ROS) produced from activated molecules, technique has been recognized as one of most promising remediation technologies in water decontamination. Functional nanocarbon materials have extensively exploited heterogeneous catalysts to drive catalytic because environmental-benign process, easy applicability, high efficiency. Nevertheless, bottlenecks processes are economical production high-performance robust carbocatalysts debatable regimes. Different active sites suggested engineered nanocarbons, corresponding mechanisms carbocatalytic ambiguous including evolution various ROS, occurrence radical nonradical reaction pathways, selectivity toward organics, tunable capacity. In this Review, we will showcase roadmap development reaction-oriented clarify arguments intrinsic sites, identification intermediates, pathways ozonation. We provide critical comments innovative strategies mechanistic investigations carbon-based molecular level (electronic structures) macroscale (kinetics), deliberate screening/capture techniques, advanced characterizations situ analysis, theoretical computations. More importantly, issues future directions be proposed rational material/system design, exploration, implementation powerful technology real wastewater treatment.

Heavy metal toxicity, sources, and remediation techniques for contaminated water and soil

Environmental Technology & Innovation, Journal Year: 2021, Volume and Issue: 25, P. 102114 - 102114

Published: Nov. 24, 2021

Arsenic is a highly toxic metalloid that extensively distributed in soils and water bodies, resulting variety of toxicity mechanisms harmful effects on humans environmental health. This paper comprehensively reviews the technological development arsenic (As) removal from wastewater contaminated soil, provides insights into challenges effective compartments. The efficiency available technologies also discussed terms their principle operation, efficiency, advantages, shortcomings. Many existing are not found economically feasible for regions interest or applicable at community level. Some techniques often responsible producing by-products. Overall, adsorption technique demonstrated high almost 100% maximum 95% removing respectively. Novel methods such as application nanotechnology polymeric ligand exchangers have been gaining traction but seem to possess limitations similar conventional non-conventional techniques.
