This investigation studied the competition effects of co-existing chlorophenols in photocatalytic reaction, and compared the results with those of individual species. From the results of the experiments, the order of relative competition superiority was 2,4-dichlorophenol > 2,4,6-trichlorophenol > 2,3,4,6-tetrachlorophenol, under a concentration of 70 mu M and neutral conditions. Moreover, 2.4-dichlorophenol showed stronger decomposition superiority whenever the individual or co-existing photocatalytic reaction was presented.
