What Are the Oxidizing Intermediates in the Fenton and Fenton-like Reactions? A Perspective
Antioxidants, 2022 The Fenton and Fenton-like reactions are of major importance due to their role as a source of oxidative stress in all living systems and due to their use in advanced oxidation technologies. For many years, there has been a debate whether the reaction of FeII(H2O)62+ with H2O2 yields OH• radicals or FeIV=Oaq.
