摘要
研究了三氯乙酸在TiO2薄膜为催化剂的光催化反应体系中发生光催化降解反应时pH值的变化与影响因素。结果表明在反应过程中pH值不断变化呈现逐渐降低的趋势,pH值条件对三氯乙酸的光催化降解反应有一定的影响,低pH值有利于反应的进行。
A study was made on the variation of pH in the photocatalytic degradation of trichloroacetic acid in a photocatalytic system with titanium dioxide thin films as catalyst. The results showed that the pH values kept changing and presented the tendency of gradually going down during the reaction, the conditions of pH had a definite influence on photoeatalytie degradation of trichloroacefic acid, the low pH values were good for the reaction.
