%X We verified that C6F6,a typical perfluorine compound,could be photocatalytic degraded by H3PW12O40.The defluorination of C6F6 was determined as a function of irradiation time,pH,initial concentration of H3PW12O40,and additives as well.The defluorination of C6F6 increased with the irradiation time.Acid condition,especially pH=1.0 is preferred.3 mL solution of 2.0×10-4 mol/L C6F6 and 5.0×10-6 mol/L H3PW12O40 was irradiated for 20 min and the defluorination of C6F6 was equal to 208.1%.O2,KMnO4 and K2S2O8 added in the solution were able to increase the defluorination of C-6F-6 via oxidating(PW12O40]4-.) The defluorination of C6F6 would decline in the presence of alcohol and aromatic compounds.
