用光化学方法去除废水中的有害有机物和金属

研究了一些有机物，如丙酮，酚，染料和茶皂角甙的光催化降解，结果表明：酚的降解与文献报导的情况基本相同，在催化剂TiO2的作用下，紫外光能有效降解纺织厂的印染废水中的染料；金属化合物对光降解反应具有很大影响；还首次试验了用光催化原理消除茶皂甙中有毒溶血素的方法。

Photodegradation of some toxic organic compounds and the influence of metallic ions

The photocatalytic degradation of some organic chemicals in water, such as acetone, phenol, dyes, and tea saponin was studied. The results of phenol photodegratation are found in agreement with the reports in literatures. Dyes in wastewater from a textile factory can be effectively degraded by photocatalysis with TiO 2 and the ultraviolet light. The metallic ions under study exert big influences on the photocatalytic degradation of organic compounds.This paper also gives the first try to eliminate the toxic hemolysin of tea saponin by photocatalytic way.
