| Abstract: | 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 photocatalytic degradation of trichloroacetic acid, the low pH values were good for the reaction. |
