Abstract: In this study, we evaluated the photocatalytic activities of analytical reagent (AR) grade iO2 to identify a low-cost photocatalyst for dye degradation.studied different conditions in the presence of iO2 suspension. The effectof various parameters such as mass of titanium dioxide, dye concentrationon the photocatalytic degradation were investigated. Results showed that, thephotocatalytic degradation process was high at the beginning and then decreased with time. This process was well described by pseudo, first order kinetics according to the Langmuir-Hinshelwood model. The results explained the photocatalytic degradation efficiency, which was increased by increasing catalyst loading from0.05 to 0.3 g/100ml. Results also showed that the rate of photocatalytic degradation was increased with decreasing dye concentration.
