Kinetic model for phenolic compound oxidation by Fenton's reagent

A kinetic model is developed for the oxidation of phenolic compounds by Fen ton's reagent. In the first stage a rigorous kinetic model is applied to ca lculate the different kinetic rate constants for the oxidation process of p -hydroxybenzoic acid. In a second phase a competitive method is applied to calculate these kineti c constants for another 10 phenolic compounds present in agroindustrial and pulp paper wastewaters. These 10 phenolic compounds were: beta -resorcylic acid, 3-(4-hydroxyphenyl)-propionic acid, ferulic acid, protocatechuic aci d, caffeic acid, p-coumaric acid, vanillic acid, syringic acid, veratric ac id and 3,4,5-trimethoxybenzoic acid.
