The Fenton reaction refers to the reaction of Fe(II) with H2O2 (Reaction 59.1). In general, •OH is known to be produced by the Fenton reaction as a reactive oxidant [9]. The generated •OH reacts rapidly with organic and inorganic constituents in water [1]. It has also been suggested that an alternative oxidant (most … See more Fe(III) exists in forms of complexes in water. In the absence of water constituents acting as ligands, Fe(III) basically forms hydroxo complexes.
