摘　　要：This paper provides evidence for the degradation of organic pollutant by the photo-Fenton complex mechanism. Both the complex oxidation and HO. oxidation mechanisms were verified by p-chlorophenol degradation, UV/Vis spectra anaylsis, and quantum yield. The hydroxyl radical involved in the photo-Fenton process can also be generated from the decomposition of H2O2, photolysis of Fe^3＋ and degradation of hydrated Fe（Ⅵ）-complex, excepting the traditional Fenton reaction.This paper provides evidence for the degradation of organic pollutant by the photo-Fenton complex mechanism.
