摘      要：Reactive oxygen species(ROSs)in Fenton process are of great importance in treating contaminants in *** is crucial to understand their chemical properties,formation,and reaction mechanisms with *** review summarizes the reactive oxygen species in Fenton process,including hydroxyl radical(·OH),superoxide radical(O_(2)·-),singlet oxygen(1O_(2)),hydroperoxyl radical(HO_(2)·),and high-valent iron.·OH shows a trend to react with chemistry groups with abundant electrons through H-atom abstraction,radical adduct formation and single electron *** transfer is discovered to be an important pathway when1O_(2)degrades organic ***-opening andβ-scission are proposed to be the possible ways of1O_(2)to certain *** abstraction,nucleophilic substitution,and single electron transfer are proposed to explain how O_(2)·-degrade *** the conjugated acid of O_(2)·-,radical adduct formation and H-atom abstraction are reported for the reaction mechanisms of hydroperoxyl ***-valent iron in Fenton,namely Fe(IV),reacts with certain pollutants via single-or two-electron *** review is important for researchers to understand the ROSs produced in Fenton and how they react with pollutants.
