Abstract:

This paper describes the basics of photocatalysis using semiconductors like TiO2 and the application of photocatalytic processes for waste water purification from different industries. The photocatalytic activity of TiO2 and CuO for the degradation of different substances under UV light irradiation. The higher phtocatalytic activity was obtained for TiO2. In the present investigation, result indicates that removal of dye methylene blue (MB) has been studied by considering influent concentration, loading of photo catalyst, pH and contact time as operating variables. The percentage removal of dye MB increase with increase in contact time. The optimum contact time was fixed at 120 minutes for TiO2 and CuO. The results of this study reveal that the dyes could be removed by semiconducting materials assisted photoatalytic degradation. The kinetics study of experimental data was analyzed using the pseudo first order kinetics and Pseudo second order model to determine adsorption rate constant.
