They have close relationship as the former may provide new ideas and approaches for the later, while the later may be the simulation for the former and gives it helps in degradation products identification and mechanism explanation. It is necessary to choose a suitable system, which has high potential of treating EDs and close relationship to the natural environment, to combine the researches in the two aspects. Our group has been engaged in researches on the photochemical properties and application to water pollution control of different ferric species including Fe -OH complexes, Fe -polycarboxylate complexes, Ferric oxides and Fe -humic acid complexes. Fe -oxalate complexes system has higher efficiency than the other ferric species systems in photooxidation and degradation of organic compounds. This thesis is focused on the photodegradation of nine EDs estradiol (E2), estrone (E1), 17α-ethynyl estradiol (EE2), diethylstilbestrol , bisphenol-A , 4-Nonylphenol , 4-Octylphenol , di-n-butyl phthalate , and di (2-ethylhexyl) phthalate .
