摘　　要：以水解法制备具有锐钛矿晶型结构的TiO2,并负载CuO。在自然光照射下,研究印染废水的光催化脱色效果及pH、H2O2用量以及CuO/TiO2用量等影响因素。实验结果表明,在自然光照射下,用CuO/TiO2降解500 mL印染废水的最佳条件是:pH值为11,CuO/TiO2用量为0.05 g,H2O2用量为5 mL,反应时间为3 h。It should prepare the TiO2 with anatase structure by hydrolyze method and CuO supported on. Photo - catalytic decolonization effect and influencing factors of printing - dyeing wastewater were tested under daylight, such as pH, H=O2 , concentrations of CuO/TiO2 and H202. The results indicated that the best conditions of photo - catalysis to treat of printing - dyeing wastewater at the volume of 500 mL were ： pH = 11, concentration of CuO/TiO2 = 0.05 g, concentration of H2 O5 = 5 mL, the reaction time = 3 hours.
