Effects of pH and substituted 1,2-dihydroxybenzenes on the reaction pathway of Fenton-like systems
The Fenton reaction is a redox cycle in which iron reacts with H2O2 to produce several reactive species, such as hydroxyl radicals (center dot OH), perhydroxyl radicals (center dot OOH), ferryl ions (Fe(IV)) and singlet oxygen (O-1(2)). The type and amount of reactive species produced by this redox system can change depending on the reaction conditions. For example, ligands, such as 1,2-dihydroxybenzene (1,2-DHB), can promote the Fenton reaction primarily by promoting the availability of Fe(II) to react with H2O2.
