A new insight into Fenton and Fenton-like processes for water treatment: Part II. Influence of organic compounds on Fe(III)/Fe(II) interconversion and the course of reactions

► Structures of target compounds affect the course of Fenton and Fenton-like reactions. ► Amounts of aromatic compounds influence the extent of Fe(III)/Fe(II) conversion. ► Aromatic intermediates influence Fe conversion and reaction process by direct or indirect reduction. ► Fenton and Fenton-like reactions may involve each other and occur simultaneously.
