Complete dechlorination and mineralization of chlorophenols via the reduction–oxidation-mediated electro-Fenton process with a composite bulk cathode is first proposed. The in situ formation PdFe nanoalloy carbon defects as key active sites mutually induced during aerogel-based electrode. Specifically, promotes generation [H]ads reduction improves electron transfer an electrical circuit, while selectively favor 2e– oxygen pathway. Notably, this work implies novel electrocatalytic model for...

The Yangtze River basin covers one-fifth of China's land area and serves as a water source for one-third population. During long-distance transport from upstream to downstream, various sources dissolved organic matter (DOM) lead considerable variation in DOM properties, significantly impacting treatability disinfection byproduct (DBP) formation after chlorination. Using size-exclusion chromatography fluorescence spectroscopy, the spatial characteristics was comprehensively investigated on...
Total organic halogen (TOX) is widely used as a surrogate bulk parameter to measure the overall exposure of halogenated disinfection byproducts (DBPs) in drinking water. In this study, we surprisingly found that level TOX chlorinated waters had been significantly underestimated under common analytical conditions. After addition quenching agent sodium thiosulfate, total chlorine and bromine exhibited two-phase decomposition pattern with increasing contact time, significant was observed for...
Widely used antioxidants can enter the environment via urban stormwater systems and form disinfection byproducts (DBPs) during chlorination in downstream drinking water processes. Herein, we comprehensively investigated occurrence of 39 from runoff to surface water. After a storm event, concentrations increased by 1.4-fold 102-110 ng/L 128-139 ng/L. Widespread event could transform into toxic DBPs disinfection. Moreover, yields trihalomethanes, haloacetaldehydes, haloacetonitriles (HANs),...
Iodinated DBPs (I-DBPs), many more toxic than regulated chlorinated and/or brominated DBPs, are a major challenge in the supply of safe drinking water. While over 800 have been identified, occurrence and precursors I-DBPs remain poorly understood. Herein, natural organic matter from two raw waters was fractionated using ultrafiltration membranes into different groups based on molecular weight (MW). The <1 kDa fraction exhibited highest levels cytotoxicity genotoxicity after disinfection....
Iodinated disinfection byproducts (I-DBPs) are of particular concern in drinking water due to the more cytotoxic and genotoxic properties than their chlorinated brominated analogs. Formation I-DBP primarily results from oxidation iodide-containing waters with various oxidants chlor(am)ination iodinated organic compounds water. This study first reports that ferric chloride (FeCl3) can lead formation coagulation (I-CBPs) resorcinol solution or natural waters. The unwanted I-CBP involved iodide...
Snow with large specific surface area and strong adsorption capacity can effectively adsorb atmospheric pollutants, which could/might lead to the increase of disinfection by-product (DBP) precursors in water. In this study, contents characteristics dissolved organic matter (DOM) meltwater were investigated, DBP formation DBP-associated cytotoxicity index during chlorination was first explored. Overall, exhibited high nitrogen contents. Meltwater-derived DOM mainly composed organics low...
