Result At the end of dioestrus, the estradiol level was increased gradually, and the peak of estradiol appeared from 1 day before oestrus to 3 days after oestrus (52.50±29.26) pg/mL, then the estradiol decreased rapidly, its lowest value at 6-9 days of oestrus (7.20±5.50) pg/mL. The level of progesterone was low before oestrus, and rose gradually at the peak of estradiol and reached the highest value at 9-15 days of oestrus (35.52±7.87) ng/mL, then it decreased gradually.

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 .

The conclusions were as follows: theνO-H andνC=O IR absorption maxima shifted towards higher wave numbers after imprinting 17β-estradiol on TFMAA-co-TRIM copolymer with the red shift of theνO-H groups being apparent after precipitation polymerization for 16h while that forνC=O groups being observed after polymerization for 24h. A strong interaction between TFMAA and 17β-estradiol was confirmed by the high selectivity for 17β-estradiol, as indicted by the values of the separation factor of isomers of 17β-estradiol/17α-estradiol (2.28) and the imprinted factor (3.01). Particle diameter of TFMAA-co-TRIM polymer was between 300 nm and 1.5μm, which suited well for solid phase sorbent throughout at low column pressure. The recognition of imprinting TFMAA-co-TRIM polymer for sterol molecules was driven by enthalpy eluted with acetronitile, and low temperature was in favor of the separation of sterol structure analogues on imprinting column. TFMAA-co-TRIM polymer possessed of determinate anti-heat stability, with melting point beginning at 255.84℃, Tp=257.40℃, control TFMAA-co-TRIM polymer and imprinting TFMAA-co-TRIM polymer were respectively decompounded at 267.79℃and 343.11℃, and solid micro-extraction noddle prepared by the special polymerization also showed definite recognition for 17β-estradiol by GC/MS detecting at 270℃. By selection of various washing and elution solvents, elution reagents of close polymerization system were of more advantage in template molecules retention and recognition on molecularly imprinted solid phase extraction column. At a certain extent, progesterone, 17α-estradiol, 17β-estradiol and 4-androstene-3, 17-dione could be intercepted on the MISPE column. Especially, MISPE had high selectivity for progesterone, and imprinting TFMAA-co-TRIM polymer could achieve adsorption balance within 50 min by absorption kinetics test for 17β-estradiol. However, MISPE column showed better selectivity and enrichment property for 17β-estradiol than C18 and CSPE columns according to the data from HPLC and GC/MS analyses. Recovery of 17β-estradiol on MISPE column was up to 85.5% while when prime extracting solution of milk powder was sampled, the recovery of CSPE and C18 columns were 43.7% and 30.7%, respectively.
