| Summary: | The kinetics of modified versions of the model of the Fenton reaction have been investigated. In these versions, radicals are produced by splitting FeO<sup>2+</sup> (dissociation product of Fe<sup>2+</sup> ozonide Fe<sup>2+</sup>O<sub>3</sub>) into Fe<sup>3+</sup> and OH<sup>.</sup> 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 FeO<sup>2+</sup> as an intermediate, accounted satisfactorily for the kinetics of the reaction under the same conditions. The amphoteric nature of FeO<sup>2+</sup> to form FeOH<sup>3+</sup> and HOFeO<sup>+</sup> in reactions with H<sup>+</sup> and OH<sup>−</sup>, respectively, extends its activity to a wide range of pH values. |
