ABSTRACT

In this research, the photocatalytic decolorization of textile wastewater, using zinc oxide as a photocatalyst was examined in the current method of removing dyes from wastewater as an ideal photocatalyst. All experiments were taken at room temperature in a batch reactor by using Ultra-Violet photo-oxidation process because of high effectiveness in color removal. The decolorization of wastewater using ZnO under various pH and different concentrations. Zinc oxide proved to be very effective catalysts in photocatalytic decolorization of real textile industrial water. The best decolorization achieved was 83% by using ZnO at room temperature, within 205 minutes of irradiations. At pH of 9.2, the maximum decolorization was 84%, so it can be called the best pH in this experiment. This study proves that real textile wastewater reacts effectively with catalyst and give good results of dyes degradation for the suspension.
