The presence and induced secondary reactions of natural organic matter (NOM) significantly affect the remediation efficacy in situ chemical oxidation (ISCO) systems. However, it remains unclear how this process relates to radicals generated from between NOM oxidants. study, for first time, reported vital roles transformation pathways carbon-centered (CCR

Natural environments subjected to hydrologically driven redox fluctuations are regarded as propitious contaminant degradation since they favor the cyclic oxygenation of Fe(II) minerals, which produces oxygen reactive species (ROS), such hydroxyl radical, OH•. However, identity these may vary a function physicochemical conditions and remains matter research. Here, using spin-trapping electron paramagnetic resonance (EPR) with 5,5-dimethyl-1-pyrroline N-oxide (DMPO) spin trap, we show that non-hydroxyl is produced in significant amounts upon air-oxidation alluvial soil suspensions (Seine River Basin, France). Indeed, among DMPO–OH•, DMPO–CO2•–, DMPO–alkyl• adducts observed, latter dramatically increases addition ethanol or, lesser extent, tert-butanol, especially phosphate buffer. This result reveals dominant species, interpret Fe(IV) it known oxidize alcohols alkyl• radicals favored by ligands. With buffer ethanol, production correlates initial reduced-state iron pool samples, determined Fe K-edge X-ray absorption spectroscopy (XAS). phyllosilicates, Fe(0) one core and, vivianite, found be most significantly oxidized phases oxygenation, pyrite appears less reactive. Hence, differing from OH•, forms presence soil-sourced phosphate. Our results therefore call further directly identify this putative investigate its ability degrade organic contaminants natural environments.
