Abstract:General kinetic relations were established for the first step of oxidation of Acid Blue 80 in weakly acidic, neutral and basic media in the following systems: Fe2+-H2O2, Mn2+-HCO3--H2O2, and Cu2+-phenanthroline-H2O2. The rate constant for the reaction of hydroxyl radical with the dye and the dependence of the degree of bleaching upon oxidant and catalyst concentrations were determined.
