固定化纳米TiO_2光催化降解粒子元青染料废水

Immobilization of nanometer TiO_2 to degrade LZYQ dye waste-water by photocatalysis

以纳米TiO2为催化剂,以砂子为载体,高压汞灯为光源,对粒子元青染料废水进行光催化降解,结果表明,锐钛型TiO2对粒子元青染料有显著的光降解作用,并且讨论了初始pH值,H2O2用量等因素对光催化反应的影响。

The photocatalysis degradation and oxidation of LZYQ dye waste-water is studied under high-pressure mercury lamp. It shows that LZYQ waste-water is remarkably photolized under the condition of the experiment. Meanwhile, the study of the relation ship between the photo-degradation and some factors are undertaken, such as initial PH of dye waste-water, the volume of H2O2 solution etc.
