Abstract

The kinetics of modified versions of the model of the Fenton reaction have been investigated. In these versions, radicals are produced by splitting FeO²⁺ (dissociation product of Fe²⁺ ozonide Fe²⁺O₃) into Fe³⁺ and OH^. The analysis shows that the revised models have the same shortcomings as the corresponding models of Haber and Weiss and of Barb et al. A nonradical model, based on an intact FeO²⁺ as an intermediate, accounted satisfactorily for the kinetics of the reaction under the same conditions. The amphoteric nature of FeO²⁺ to form FeOH³⁺ and HOFeO⁺ in reactions with H⁺ and OH⁻, respectively, extends its activity to a wide range of pH values.
