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、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500ml印染废水的最佳条件为：pH值为11，CuO/TiO2用量为0.05g, H2O2用量为5ml,反应时间为3个小时。Abstract
Preparing the TiO2 with anatase structure by hydrolyze method and with CuO supported on.Photocatalytic decolorization effect and influence factors of dyeing wastewater were reseached under daylight, such as Ph、H2O2、concentration of CuO/TiO2 and H2O2.The result indicated that the best condition of photocatalysis dedradation of dyeing wastewater at the volume of 500ml was:pH=11,concentration of CuO/TiO2=0.05g, concentration of H2O2=5ml,the reaction time=3 hours. 关键词
