In this study, the kinetics equation describing heterogeneous photocatalytic process in relation with the absorption of radiation by inactive photochemically reagents was presented. The proposed expression was verified based on the results of degradation process of selected azo-dyes. The experiments were carried out in one- and two component solutions in the presence of TiO2 (anatase) during UV-a irradiation.
