Facet tailoring and Cu doping promoted photo-assisted peroxymonosulfate activation by oxygen-deficient α-MnO2 for efficient mineralization of bisphenol a

Jinpeng Wang et al.

Summary: In this study, the synergistic effects between Cu doping and crystal facets on the activation of peroxymonosulfate (PMS) for bisphenol A (BPA) degradation were investigated. Cu-doped α-MnO2 with different facets showed that Cu-doped (11 0) had the highest BPA removal efficiency with high 1O2 generation and selectivity. Cu doping enhanced light absorption, the formation of oxygen vacancies and conductivity, leading to improved PMS activation.

Assessing the Use of Probes and Quenchers for Understanding the Reactive Species in Advanced Oxidation Processes

Yu Lei et al.

Summary: Advanced oxidation processes (AOPs) are widely used for water and wastewater treatment. This study determined second order rate constants for reactions between probes and quenchers with various reactive species and chemical oxidants. Previously ill-quantified reactions were found to be favorable. The improved kinetic database and proposed criteria for probe and quencher selection and dosing will benefit future research in AOPs and other radical-involved reactions.

Decoupling Fe0 Application and Bioaugmentation in Space and Time Enables Microbial Reductive Dechlorination of Trichloroethene to Ethene: Evidence from Soil Columns

Srivatsan Mohana Rangan et al.

Summary: This study investigates the efficacy of coupling Fe0 with H2-utilizing organohalide-respiring bacteria (D. mccartyi) for the remediation of chlorinated solvents. By decoupling the application of Fe0 from organic substrates and D. mccartyi-containing cultures, the study demonstrates that reduced groundwater from Fe0 can support microbial reductive dechlorination and achieve high conversion rates of trichloroethene to ethene. The findings suggest that separating the application of Fe0 and biostimulation/bioaugmentation in space and time can enhance microbial trichloroethene reductive dechlorination, particularly in oxic conditions.

Regulating the concentration of dissolved oxygen to achieve the directional transformation of reactive oxygen species: A controllable oxidation process for ciprofloxacin degradation by calcined CuCoFe-LDH

Shaohong Wang et al.

Summary: Different reactive oxygen species (ROS) attack specific sites on pollutants and form intermediates with different toxic effects. The mechanism and transformation path of ROS regulation are still unclear. This study controlled the dissolved oxygen (DO) content and showed that increasing DO concentration promotes the conversion of superoxide radical (center dot O-2(-)) to hydroxyl radicals (center dot OH). This work provides a new perspective on wastewater treatment by controlling ROS generation through regulating DO concentration.

Layered double hydroxide driven 1O2 non-radical or 'OH radical process for the degradation, transformation and even mineralization of sulfamethoxazole via efficient peroxymonosulfate activation

Fan Wu et al.

Summary: In this study, the degradation of sulfamethoxazole was regulated using layered double hydrotalcite and different reactive oxygen species. It was found that 1O2 and 'OH groups could enhance the removal efficiency and mineralization efficiency of sulfamethoxazole. The coupling of 1O2 and 'OH radicals achieved complete removal and mineralization of sulfamethoxazole, with removal efficiency reaching 100% and mineralization efficiency reaching 24.8%. The degradation behavior and kinetics of sulfamethoxazole could be controlled through sequential direct oxidation, 1O2, and 'OH treatment, improving the utilization efficiency of PMS. The interfacial PMS activation process was responsible for regulating the non-radical and radical processes.

Iron cycle tuned by thiosulfate in Fenton reactions: Kinetic modelling and mechanisms

Nan Li et al.

Summary: The addition of metal-free reducing agent thiosulfate (S2O32-) in Fenton reaction effectively addresses the issues of Fe(III) precipitation and slow Fe(III) reduction. The degradation of sulfamethoxazole (SMX) is significantly accelerated over a wide pH range (3.0-7.0) by S2O32-. The complexation and reduction role of S2O32- prevents the precipitation of iron ions and accelerates the reduction of Fe(III), leading to enhanced SMX degradation.

Role of halide ions on organic pollutants degradation by peroxygens-based advanced oxidation processes: A critical review

Ying Xue et al.

Summary: This review reconciles conflicting data on the degradation of pollutants in the presence of halides by peroxygens-based AOPs. Halide ions were found to affect contaminants' degradation either negatively or positively, depending on various factors such as substrate properties and operating parameters. Further research is needed to understand the effect of halides on the simultaneous removal of multiple organic pollutants. Better AOP technologies should be selected to minimize adverse effects and take advantage of positive effects in order to reduce operating costs and emissions in saline environments.

Synthesizing and characterizing Fe3O4 embedded in N-doped carbon nanotubes-bridged biochar as a persulfate activator for sulfamethoxazole degradation

Tong Liu et al.

Summary: Nitrogen-doped magnetic carbon nanotubes-bridged biochar (Fe3O4@NCNTs-BC) was prepared and showed excellent capacity in activating persulfate for sulfamethoxazole (SMX) degradation. A direct electron transfer regime involving surface-bound metastable complexes was found to play a decisive role in the Fe3O4@NCNTs-BC800/peroxydisulfate (PDS) system. The differences in degradation performances and activation regimes were attributed to the surface hydroxyl groups of carbon-based catalysts and the structure discrepancies between PMS and PDS.
