Experimental results on photobleaching of Chicago Sky Blue diazo dye solutions using ZnO/ZnAl2O4/Cu photocatalytic nanocomposites are presented. Data on the crystal structure and morphology of these nanocomposites obtained by the polymer-salt method are presented. The results of studies of the kinetics of the processes of photobleaching of dye solutions and its adsorption on the surface of powdered nanocomposites showed that the experimental data correspond to known kinetic models using the first and second order rate equations for these processes. Keywords: dye, photobleaching, solution, photocatalysis, adsorption. DOI: 10.61011/EOS.2023.03.56190.4154-22
