✦ Synopsis

An improved kinetic model ofcatalytic oxidation of tetravalent sulphur in aqueous solutions has been suggested, based on oxygen absorption experiments carried out in a stirred tank with a plane interface. The model comprises a chemical network of catalyst (manganous soluble salt) transformations and a set of step rate equations with the appropriate kinetic constants determined. It indicates the possible enhancement of tetravalent sulphur oxidation by applying conditions of the manganous dimer maximum concentration.
