| 摘 要： | 以10W直管紫外杀菌灯为光源,固定在泡沫镍上的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行为。以丙酮为光催化降解对象,结果表明丙酮的降解符合准一级动力学方程,并研究了多种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。

Studies on the Photocatalytic Degradation of Acetone Solution Using TiO2 Supported on Porous Nickel |
| |
| Abstract: | With one 10W ultraviolet sterilized lamp as light source, by the catalysis of titanium dioxide which immobilized on porous nickels, an investigation of the photocatalytic degradation of the organic pollutants with low boiling point has been studied. The results showed that the degradation of acetone in aqueous solution accorded with first order kinetics equation. Other influence on the photo degradation of the acetone has also been studied and analyzed. A new photoreaction has been designed to the same organic pollutants as acetone. |
