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.
通过研究阐明:紫外聚合产物TFMAA-co-TRIM中的νO-H振动吸收峰在聚合16h后红移,νC=O振动吸收峰在聚合24h后红移;TFMAA-co-TRIM对雌二醇异构体的印迹因子达到了3.01,α为2.28,优于其它功能单体参与得到的聚合物识别特性;TFMAA-co-TRIM聚合物粒径介于300 nm至1.5μm之间,作为色谱固定相具有良好的通量和低的柱压;在乙腈流动相中,TFMAA-co-TRIM分子印迹固定相的分离过程主要被焓驱动,低温有利于分子印迹固定相分离甾醇结构类似物;TFMAA-co-TRIM分子印迹聚合物在255.84℃时开始熔融,Tp=257.40℃,聚合物CP的降解温度在267.79℃,MIP降解温度在343.11℃,制备的固相微萃取头初步经GC/MS 270℃的耐热性测定;不同的洗提溶剂筛选证明了选择接近聚合溶剂的洗脱体系更有利于MISPE发挥识别效应;分子印迹固相萃取柱对孕酮、17α-雌二醇、17β-雌二醇和雄烯二酮都具有不同程度的保留特性,可作为此类化合物的吸附材料,特别对孕酮强保留的富集特性,可作为孕酮的选择性识别吸附剂,其分子印迹聚合物对17β-雌二醇的吸附动力学测定显示在50 min内基本达到吸附平衡,具有作为传感器核心敏感材料的潜力;对比萃取奶粉中17β-雌二醇性能,MISPE柱比非分子印迹固相萃取柱和C18柱具有更高的保留,回收率依次为85.5%,43.7%和30.7%。
