%X The photocatalytic oxidation of phenol in TiO_2 particle suspensions has been studied in atest reactor illuminated with a 5000 W medium pressure mercury lamp.Eight main productshave been identified by HPLC, IC,TOC and GC /MS.The results indicated that there arethree stages of reaction from the viewpoint of products distribution, there are hydroxyla-tion,carboxylation and mineralization,The oxidation process could be explained nd justifiedby means of coricentration variation of main products like pyrocatechol,fumaric acid andCO_2 and the carbon mass balance achieved 94.4%,The effects of CO_2 concentration in gas phase on the phenol decomposition and products distribution have been investigation.
