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. (C) 2001 Elsevier Science Ltd. All rig
