摘要
研究了以黄砂为载体,TiO_2为催化剂,以太阳光为光源对邻氯苯酚水溶液进行光催化降解的可行性。结果表明,锐钛型TiO_2对邻氯苯酚有显著的光催化降解作用; TiO_2的催化活性在焙烧温度300℃时最高。此外还探讨了pH值、TiO_2的附着量、邻氯苯酚溶液浓度等因素对光催化反应的影响。
The photocatalytic degradation and oxidation of aqueous o-chlorophenol solution had been studied under sunlight in simulating shallow ponds. The photocatalyst was titanium dioxide immobilized on sand. It showed that o-chlorophenlo was remarkably photolized under the condition of the experiment. The influence of parameters, such as initial concentration, pH of o-chlorphenol solution, the quantity titania for adhesion and the volume of o-chlorophenol solution, had been studied.
