In this work, sensitized titanium dioxide powders was prepared using different weight of azocaramine G dye (0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7 and 1) g. Each weight of dye mixing with 1 g of titanium dioxide using a Pyrex reactor (100 cm3), irradiated with tungsten lamp at 298 K with 10 cm3/min air flow. Different experiments were carried out at various conditions to reach the optimum condition in which the degradation of Congo red dye was studied. These experiments include the alternate concentration of Congo red, on fixed mass of sensitized titanium dioxide, change the dosage of sensitized titanium dioxide and the effect of light intensity.
