摘要：

以10W直管紫外杀菌灯为光源, 以泡沫镍基纳米TiO₂为催化剂, 研究了低沸点有机小分子污染物的光催化降解。以丙酮为光催化降解对象, 结果表明, 丙酮的降解符合Langmuir Hinshelwood准一级动力学方程, 并研究了相关因素对丙酮的光催化降解的影响, 并对实验现象加以解释。实验还对类似于丙酮的低沸点有机污染物, 设计了一种新颖的光催化反应器。

Abstract:

With one 10 Wultraviolet sterilized lamp,and by using titanium dioxide as catalysis, which is immobilized on porous nickels, an investigation of the photocatalytic degradation of the organic pollutants with low boiling point had been studied. The research results show that the degradation of acetone in aqueous solution accords with the first pregrade kinetics equation. Other influence on the photo degradation of the acetone has also been investigated and explained. A new photoreaction has been devised for the same organic pollutants to acetone.

Key words: titanium dioxide, photocatalysis , acetone, porous nickel
