摘要：

The degradation of acetic acid, monochloroacetic acid and dimethyl-2,2,2-trichloro-1-hydroxyethylphosphonate (DEP) by ozonation on illumination was enhanced considerably by the incorporation of photocatalyst. This effect was smaller for the degradation of phenol. However, intermediate organic acids formed during the degradation of phenol disappeared rapidly with the incorporation of photocatalyst. It is suggested that the effect of the photocatalyst is larger on the degradation of hydrophilic compounds than aromatic compounds.
