摘要: In this study the photocatalytic decomposition of a synthetic dye, C. I. Acid Yellow 17, was investigated. The TiO2 photocatalyst prepared by chemical vapor deposition (CVD) for UV/TiO2 process was prepared by annealing at 550 degrees C for 24 h and anatase type crystalline (under XRD and SEM analysis) was obtained. The more important factors affecting the dye wastewater treatment in terms of dye removal ratio, color removal ratio, and mineralization ratio in this study were pH value of the solution, initial concentration of the dye wastewater, flow rate of the wastewater inflow and light intensity. Chloride and sulfate were detected in C. I. Acid Yellow 17 decomposition process while ammonium and nitrate were not detected. (c) 2005 Elsevier Ltd. All rights reserved.
