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 .
因此从处理效率和环境化学意义两方面考虑,结合本课题组在不同铁形态(包括Fe-OH配合物、Fe-多羧酸配合物、Fe氧化物、Fe-腐殖酸配合物等)的光化学特性及其在水污染控制中的应用方面较系统的研究工作基础,本论文选择了四类共9种典型的内分泌干扰物(雌二醇(E2)、雌酮(E1)、17α-乙炔基雌二醇(EE2)己雌酚、双酚A、壬基酚、辛基酚、酞酸二丁酯和酞酸二乙基己基酯),研究了它们在Fe-草酸盐配合物体系中的光降解效果,推测其降解机理,探索环境内分泌干扰物光氧化处理的新体系,同时为预测其在环境中的光降解行为提供了依据。
