| 摘 要： | 采用光催化荆Y2O3/WO3对含溴酚蓝染料废水的处理进行了研究,探讨了光催化剂作用机理,讨论了光催化剂组成、用量、试液pH值、光照时间与溴酚蓝染料溶液脱色率的关系.结果表明,当w(Y2O3)=1.5%、50mL时试液的起始质量浓度为20mg/L,催化剂用量为0.400g,pH=7.0,光照6h时溴酚蓝染料溶液的脱色率可达96.8%.

| Abstract: | The treatment of waste water containing bromphenol blue(BPB) using Y2O3/WO3 is studied.Reaction mechanism of photocatalysis is probed.The relationships between the composition of heterogeneous photocatalyst,pH,illumination time and the decolorizing rate of BPB are discussed.The results show that the decolorizing rate of BPB can reach 96.8% using Y2O3/WO3 as heterogeneous photocatalyst when w(Y2O3) is 1.5%,initial concentration of 50mL BPB is 20mg/L,amount of catalyst is 0.400g,pH value is 7.0,illumination t... |
