Advanced oxidation processes (AOPs) are increasingly applied in water and wastewater treatment. Understanding the role of reactive species using probes quenchers is one main requirements for good process design. However, much fundamental kinetic data reactions with lacking, probably leading to inappropriate probe quencher selection dosing. In this work, second-order rate constants over 150 such as •OH, SO4•-, Cl• chemical oxidants free chlorine persulfate were determined. Some previously...
Chlorine radicals, including Cl• and Cl2•-, can be produced in sunlight waters (rivers, oceans, lakes) or water treatment processes (e.g., electrochemical advanced oxidation processes). Dissolved organic matter (DOM) is a major reactant with, scavenger of, Cl2•- water, but limited quantitative information exists regarding the influence of DOM structure on its reactivity with Cl2•-. This study aimed at quantifying reaction rates formation chlorinated byproducts from reactions DOM. Laser flash...
Bromine radicals can pose great impacts on the photochemical transformation of trace organic contaminants in natural and engineered waters. However, reaction kinetics mechanisms involved are barely known. In this work, second-order rate constants with Br• Br2•– were determined for 70 common 17 model compounds using laser flash photolysis steady-state competition kinetics. The kBr• values ranged from <108 to (2.86 ± 0.31) × 1010 M–1 s–1 kBr2•– <105 (1.18 0.09) 109 at pH 7.0. Six quantitative...
Abstract Designing water‐deficient solvation sheath of Zn 2+ by ligand substitution is a widely used strategy to protect metal anode, yet the intrinsic tradeoff between nucleation/dissolution kinetics and side hydrogen evolution reaction (HER) remains huge challenge. Herein, we find boric acid (BA) with moderate field interaction can partially replace H 2 O molecules in , forming stable sheath. It enables fast substantially suppressed HER. Crucially, systematically comparing strength...
Dissolved organic matter (DOM) scavenges sulfate radicals (SO4•–), and SO4•–-induced DOM transformations influence disinfection byproduct (DBP) formation when chlorination follows advanced oxidation processes (AOPs) used for pollutant destruction during water wastewater treatment. Competition kinetics experiments transient were conducted in the presence of 19 fractions. Second-order reaction rate constants reactions with SO4•– (kDOM,SO4•–) ranged from (6.38 ± 0.53) × 106 M–1 s–1 to (3.68...
Dissolved organic matter (DOM) is a major scavenger of bromine radicals (e.g., Br• and Br2•-) in sunlit surface waters during oxidative processes used water treatment. However, the literature lacks quantitative measurements reaction rate constants between DOM information on extent to which these reactions form brominated byproducts. Based transient kinetic analysis with different fractions sources DOM, we determined for ranging from <5.0 × 107 (4.2 ± 1.3) 108 MC-1 s-1, are comparable those...

Dissolved organic matter (DOM) has been known to inhibit the degradation of trace contaminants (TrOCs) in advanced oxidation processes but quantitative understanding is lacking. Adenine (ADN) was selected as a model TrOC due wide occurrence purine groups TrOCs and well-documented transient spectra its intermediate radicals. ADN presence DOM during UV/peroxydisulfate treatment quantified using steady-state photochemical experiments, time-resolved spectroscopy, kinetic modeling. The inhibitory...
Wastewater effluent is a major source of extracellular antibiotic resistance genes (eArGs) in the aquatic environment, threat to human health and biosecurity. However, little known about extent which organic matter wastewater (EfOM) might contribute photosensitized oxidation eArGs. Triplet states EfOM were found dominate degradation eArGs (accounting for up 85%). Photo-oxidation proceeded mainly via proton-coupled electron transfer reactions. They broke plasmid strands damaged bases. O2•–...

The NO3•-driven nighttime aging of brown carbon (BrC) is known to greatly impact its atmospheric radiative forcing. However, the oxidation by NO3• on optical properties BrC in waters as well associated reaction mechanism remain unclear. In this work, we found that variation proxies under environmentally relevant exposure depends strongly their sources, with enhanced light absorptivity for biomass-burning but bleaching urban aerosols and humic substances. High-resolution mass spectrometry...
