In this work, a novel strategy for Fenton activity improvement of Cu2X was reported, in which the local electron density Cu sites regulated via manipulation simple chalcogen elements (O, S, and Se). Among them, Cu2Se catalysts show excellent catalytic to activate H2O2 complete removal ofloxacin (10 mg/L) at an initial pH 6.5 within 120 min. Radical scavenger experiments spin resonance spectroscopy confirm that •OH radicals are primary oxygen reactive species drive degradation. addition, functional theory calculations further proved electrons would migrate from X accumulate on active order Se > S O. Compared with Cu2O Cu2S, highly concentrated atoms not only decreased activation energy Fenton-like reaction but also boosted Cu2+/Cu+ cycle generation more (18-66 μm) maintenance high stability catalysts, leading application potential. We believe work will lay foundation designing practical applications since developing heterogeneous system highest oxidation efficiency has always been long-term goal field.

Substandard industrial production and accidental leaks can lead to serious groundwater contamination. In particular, organic pollutants produce continuous pollution in endanger human health. Sustained release materials (SRM) have a lower rate longer period prolong the process of chemical oxidation. At same time, they certain load capacity that is sufficient overcome lack oxygen carbon sources microbial low-temperature environments. SRM has proven be highly potential remediation material due its excellent physical properties. Its combination with traditional in-situ methods become preferred technology for more contaminated site cases. This article reviews types proportion recent years, explores feasibility as an oxidant oxidation stable source process, different forms laboratory situations. Kinetic parameters release. Of particular interest discussion available parametric data opportunities challenges large-scale applications from scale field test scale. good application prospects future there are potentially applicable technical improvements. For example, key issues need solved use stability adhesives active components under complex geological environmental conditions their fragile Utilize safely, taking into account related cost feasibility.

An electrochemically (EF) coupled advanced oxidation process for enhancing sludge dewatering by introducing oxalic acid (OA) at neutral pH was proposed. The specific resistance and water content of under the optimal conditions (reaction time 40 minutes, current intensity 1.00A, OA dosage 0.18 g/g TSS, CaO2 0.14 value 7.78) were reduced 96.9% 30.1%, respectively. presence counteracted increase in solution caused electrochemistry dosing, allowing to remain a or acidic state almost all times. Therefore, EF-CaO2/OA system can effectively improve performance without changing raw sludge. In addition, had synergistic effect on assisting electrochemical reaction promote conversion Fe3+ into Fe2+ as well accelerating dissolution CaO2, which further ensured continuous generation ·OH. organic components treated extracellular polymers changed. particular, subtle changes secondary structure proteins change from hydrophilic hydrophobic gradually. decrease zeta potential particle size contact angle indicated significant improvement performance. persistence stability reactions during conditioning also suggested that may be an efficient feasible technology new combinations.
