Bstract TiO2 photocatalyst was prepared by the sol-gel method at a temperature of 300° C and characterized by SEM with EDS and FTIR. The photocatalytic degradation of Alizarin Red S (ARS) and Bismarck Brown R (BBR) was carried out using prepared TiO2 photocatalyst irradiated with 16 W UV light source. The effect of various parameters, i.e., photocatalyst concentration, dye concentration, and pH of the solution on the percentage of degradation of selected dyes has been examined. The kinetic analysis of photodegradation of ARS and under different initial concentration followed the Langmuir-Hinshelwood model. TiO2 can be an excellent photocatalyst candidate for the degradation of the selected dyes under UV light irradiation.
