This research aims to study the efficiency of color and COD removal in wastewater from dyestuff industry by photocatalytic process under UVA light irradiation. Four types of thin film photocatalyst including TiO2, 0.3%Fe-TiO2, 0.5%Fe-TiO2 and 0.7%Fe-TiOwere prepared by sol-gel method. The wastewater used in this study for photocatalytic activity test comprised of pre- and post-treatment wastewater from the wastewater treatment plant of dyestuff industry. The results of photocatalytic activity tests indicated that the 0.5%Fe-TiO2 thin film photocatalyst was the most effective in color and COD removal with the efficiency of 14.48% and 29.29% for pre-treatment wastewater and with the efficiency of 72.11% and 54.22% for post-treatment wastewater at 180 minutes. Finally, the kinetics of photocatalytic reactions were able to describe by the Langmuir Hinshelwood model, which is a common model used to describe the kinetics of reactions that involved photocatalyst.
