Popis: | The photodegradation of 2-chlorobenzoic acid (2-CBA) in suspensions of TiO2 was examined under different operational parameters. The optimal condition could be obtained through the experiment, i.e. that the concentration of 2-CBA was 30 mg/L and the dosing quantity of TiO2 was 0.01 g under UV light in the case of pH 3.5. Above reaction process was in accordance with first order kinetics model. The influence on photocatalytic degradation caused by typical anions in eutrophicated water body such as NO3− and H2PO4− was explored in this work, which revealed that both two anions had inhibitory effect on the degradation process. In addition, alcohol was introduced into the process to identify the degradation mechanism of 2-CBA with TiO2, and the reaction route of 2-CBA could be predicted through the analysis on the intermediate. |
