Abstract
The kinetic patterns of the photocatalytic oxidation of thiocyanates by persulfate under the influence of quasi-solar ultraviolet radiation (UV) were investigated. The influence of the main factors (pH, temperature of the reaction medium, nature of the catalyst, exposure time) on the efficiency of the oxidation of thiocyanates in the combined system {UV/S2O82–/Fe3+} was studied. It was established that the process of photocatalytic oxidation of thiocyanates proceeds via the ion-radical mechanism with the participation of reactive oxygen species generated in situ, mostly hydroxyl radicals and sulfate anion radicals.
