A carbon-based advanced oxidation process is featured for the nonradical electron-transfer pathway (ETP) from electron-donating organic compounds to activated persulfate complexes, enabling it as a green technology selective of pollutants in complex water environments. However, thermodynamic and kinetic behaviors regime had been ambiguous due neglect influence pH on mechanisms. In this study, three kinds were divided ETP regime: (i) physio-adsorption, (ii) adsorption-dominated (oxidation rate slightly surpasses adsorption rate), (iii) oxidation-dominated outpaces rate). The differential attributed physicochemical properties pollutants. For example, hydrophobicity, molecular radius, positive electrostatic potential controlled mass-transfer stage reactants (peroxydisulfate (PDS) organics). Meanwhile, other descriptors, including Fukui index, potential, electron cloud density regulated processes thus kinetics oxidation. Most importantly, pathways these could be altered by adjusting chemistry. This study reveals principles developing efficient systems selectively remove recycle wastewater.

This perspective presents the latest advancements in selective polymerization pathways advanced oxidation processes (AOPs) for removal of featured organic pollutants wastewater. In radical-based homogeneous reactions, SO4• –-based systems exhibit superior oxidative activity toward aromatics with electron-donating substituents via single electron transfer and radical adduct formation (RAF). The produced cations subsequently undergo coupling reactions to produce polymers. For •OH-based oxidation, metal ions facilitate production monomer radicals RAF. Additionally, heterogeneous catalysts can mediate both persulfate activation without generating inorganic radicals. Metal-based will a direct pathway polymerization. contrast, carbon-based induce low-molecular-weight oligomers (≤4 units) an process. comparison mineralization, remarkably reduce peroxide usage, quickly separate from aqueous phase, generate polymeric byproducts. Thus, AOP-driven hold significant promise reducing carbon emission realizing recycling water treatment processes.

Oxidative polymerization versus degradation of organic pollutants in heterogeneous catalytic persulfate chemistry

Water Research, Год журнала: 2024, Номер 255, С. 121485 - 121485

Опубликована: Март 18, 2024

Catalytic polymerization pathways in advanced oxidation processes (AOPs) have recently drawn much attention for organic pollutant elimination owing to the rapid removal kinetics, high selectivity, and recovery of carbon from wastewater. This work presents a review on regimes AOPs their applications wastewater decontamination. The mainly highlights three critical issues reactions induced by persulfate activation (Poly-PS-AOPs), including heterogeneous catalysts, pathways, properties substrates. dominant influencing factors selection reactive oxygen species, substrates are discussed detail. Moreover, we systematically demonstrate merits challenges Poly-PS-AOPs upon degradation polymer synthesis. We particularly highlight that technology could be promising treatment industrial containing heterocyclic organics synthesis polymers polymer-functionalized materials environmental energy applications.
