Engineering 2023, Volume 30, Issue 11,   Pages 144-152 doi: 10.1016/j.eng.2022.12.005

Abstract: micropollutants decontamination that is solely based on sequential electrochemistry involving ubiquitous sulfateThis can be achieved via a chain reaction initiated by electrocatalytic anodic sulfate (SO4O82−) and followed by a cathodic persulfate reduction to produce sulfateradicals (SO4·).This work provides the first proof-of-concept demonstration using ubiquitous sulfate for micropollutants

Decontamination of Cr(VI) facilitated formation of persistent free radicals on rice husk derived biochar

Kaikai Zhang, Peng Sun, Yanrong Zhang

Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 2, doi: 10.1007/s11783-019-1106-7

Abstract:

PFRs were produced on biochar during Cr(VI) decontamination.

PFRs formation on biochar was owing to the oxidization of phenolic-OH by Cr(VI).

Appearance of excessive oxidant led to the consumption of PFRs on biochar.

Biochar charred at high temperature possessed great performance to Cr(VI) removal.

Frontiers of Environmental Science & Engineering 2019, Volume 13, Issue 3, doi: 10.1007/s11783-019-1122-7

Abstract:

Antibiotic-resistant bacteria and antibiotic resistance genes are in water bodies.

UV/chlorination method is better to remove ARGs than UV or chlorination alone.

Research on UV/hydrogen peroxide to eliminate ARGs is forthcoming.

UV-based photocatalytic processes are effective to degrade ARGs.
