Industrial effluents from alkaline sulfite treatment of wood contain several compounds that are recalcitrant to microbiological treatment (aromatic derivatives from wood extractives and labile lignin fractions) thus requiring a suitable treatment system [1]. Advanced Oxidation Processes (AOP) exploit the high reactivity and low selectivity of hydroxyl radicals (?OH), which attacks organic molecules during oxidation. The information regarding the kinetic study on the degradation of mixed recalcitrant compounds in industrial streams by Fenton-type oxidation is still limited; therefore, the principal objective of this work was to propose a kinetic model for the reaction.
