Cobalt-doped alumina catalyst was synthetized using the sol-gel method, gelled and calcined at 500 °C. The synthesized material was previously fully characterized. Cobalt-doped alumina was tested as catalysts in an Orange G degradation in the presence of Oxone®. Oxone® is a precursor of radicals and the role of the investigated catalyst was to activate its decomposition. Sulfate ion radicals act as oxidizing species in dye degradation reaction. The influence of the mass of the catalyst and the reaction temperature was investigated. The catalyst mass and temperature increase were beneficial for the dye degradation rate. The pseudo-first order kinetic model was found to be the most appropriate fit for experimentally obtained data. The adsorption of the dye on Co-doped alumina was also tested, and it was found to be negligible. The investigated catalyst was found to be effective for Orange G degradation in the presence of Oxone®.
