Dyes are one of the wastewater pollutants that use of them is increasing every day. In this study, the dye degradation efficiency with Zn-TiO2 was investigated using the sun as a light source. The effect of zinc on dopant activity and kinetics of dye degradation from wastewater was also investigated. Dopant was made with synthesis induction- evaporation method. The experiments were performed in a continuously photo reactor throughout the day. According to the results, at pH of 6.9, 50 mg /L of dye concentration, 50 mg/m2 catalyst concentration and Zn /Ti equal to 53% within 5 h; dye removal and organic degradation efficiency were obtained 85 and 60 %, respectively. According to the results, the reaction kinetics was pseudo-first-order equation.
