For several decades, the methodology of complete destruction organic pollutants via oxidation, i.e., mineralization, has been rooted in real water treatment applications. Nevertheless, this industrially accepted protocol is far from sustainable because excessive input chemicals and/or energy as well unregulated carbon emission. Recently, there have emerging studies on removal a completely different pathway, polymerization, meaning that target undergo oxidative polymerization reactions to generate polymeric products. These collectively shown compared conventional mineralization pathway allows more efficient pollutants, largely reduced chemicals, and suppressed In review, we aim provide comprehensive examination fundamentals process, current state-of-the-art strategies for regulation both kinetic thermodynamic perspectives, resource recovery formed end, limitations process pollutant are discussed, with perspectives future studies. Hopefully, review could not only critical insight advancement polymerization-oriented technologies greener manner but also stimulate paradigm innovations low-carbon treatment.

High-valent metal-oxo species (HMOS) have been extensively recognized in advanced oxidation processes (AOPs) owing to their high selectivity and chemical utilization efficiency. However, the interactions between HMOS halide ions sewage wastewater are complicated, leading ongoing debates on intrinsic reactive impacts remediation. Herein, we prepared three typical HMOS, including Fe(IV), Mn(V)-nitrilotriacetic acid complex (Mn(V)NTA) Co(IV) through peroxymonosulfate (PMS) activation comparatively studied with Cl

Antibiotic residues in water environments have garnered widespread attention. Metal-organic frameworks (MOFs) found extensive applications purification. This study investigates the use of a cobalt-based MOF material, zeolitic imidazolate framework-67(ZIF-67)(Co), for activating persulfate (PMS) to remove residual antibiotic ciprofloxacin (CIP) from aqueous environments. The main findings are as follows: ZIF-67(Co) exhibits insignificant adsorption capacity CIP, and PMS alone does not degrade CIP effectively. However, ZIF-67(Co)-activated demonstrates efficient degradation following pseudo-second-order reaction kinetics. Under optimal conditions catalyst dosage (15 mg) concentration (1.0 mM), removal efficiency reaches 88% after 60 min. Comparative analysis at different initial pH levels shows that highest is reached under mildly acidic conditions, with an 86% rate achieved within min these conditions. Investigation into impact various inorganic anions on ZIF-67(Co)-catalyzed reveals significant inhibition by chloride ions (Cl−), whereas nitrate (NO3-) sulfate (SO42-) minor effects efficiency. system consistent performance across matrices, highlighting ZIF-67(Co)/PMS effective environmental waters. provides technical support residues.

The utilization of biochar-catalyzed peroxymonosulfate in advanced oxidation processes (BC-PMS AOPs) is widely acknowledged as an effective and economical method for mitigating emerging contaminants (ECs). Especially, state-of-the-art machine learning (ML) technology has been employed to accurately predict the reaction rate constants EC degradation BC-PMS AOPs, primarily focusing on three aspects: performance prediction, operating condition optimization, mechanism interpretation. However, its real application specific optimization targeting different ECs seldom considered, hindering realization contaminant-oriented AOPs. Herein, we propose a hierarchical ML pipeline achieve end-to-end (E2E) pattern addressing this issue. First, overall XGB model, trained with comprehensive data set, can perform well predicting additionally providing basis further analysis various ECs. Then, submodels clusters offer strategies selection optimum option AOPs HOMO-LUMO gaps, thus forming E2E This study not only increases our understanding but also successfully bridges gap between model development environmental application.

Although metal clusters are generally considered as impurities accompanying the synthesis of single atom catalysts, their extraordinary potential in regulating catalytic reactions has attracted widespread attention. In this study, iron cluster decorated catalyst (Fe-SACAs) were synthesized to activate peroxymonosulfate (PMS) for removal organic pollutants, and a differential PMS activation mechanism induced by selective adsorption pollutants was observed first time. The chemical coordination between active sites identified dominant chemisorption Fe-SACAs. competitive occupation diversity targeted pollutant molecules ionization potentials thereby revealed be inducement adsorption-dependent oxidation. oxidation fully elucidated using density functional theory (DFT). Finally, an optimized treatment process proposed based on mechanism, which achieved zero oxidant residue emission simultaneously. This study unveils crucial effect reactant mass transfer Fe-SACAs mediated Fenton-like reactions.
