实验采用原位聚合法以甲基丙烯酸(MAA)为功能单体,乙二醇二甲基丙烯酸酯(EDMA)为交联剂,偶氮二异丁腈(AIBN)为引发剂,正十二醇和甲苯为致孔剂直接在液相色谱柱中制备了氨基安替比林分子烙印柱.讨论了模板分子及其类似物在有机相和水相中的色谱行为及作用机理.实验表明,在水相中烙印柱具有很强的保留性能,氨基安替比林的保留因子可达到94.41.结果认为离子作用和疏水作用是使得氨基安替比林及类似物具有很强的保留性的重要原因,为研究模板聚合物的结合特性,采用前流分析法分别测定了氨基安替比林、氨基比林和安替比林在烙印柱上的吸附等温线.实验表明,分子烙印聚合物对烙印分子表现了较高的选择性,这和通过比较各物质在分子烙印柱和空白柱上保留因子所获得的结果一致.

Aminoantipyrine imprinted column was prepared by in situ polymerization in a 50 mm×4.6 mm I D. stainless steel column. Methacrylic acid (MAA), ethylene glycol dimethacrylate (EDMA), 2,2'-azobisisobutyronitrile (AIBN) were used as the monomer, crosslinker and initiator, respectively. Dodecanol and toluene were used as porogen. Both organic and aqueous mobile phases were applied for the evaluation of the chromatographic character of the column, and the mechanism of molecular recognition was discussed. It was found that the imprinted column showed high selectivity towards aminoantipyrine in aqueous medium. Ionic and hydrophobic interactions were presumed as the reasons for the molecule recognition in aqueous medium. Under the optimum condition, the retention factor of aminoantipyrine could achieve 94 41. Rectangular pulse frontal analysis method was adopted to determine the single component absorption isotherms. In contrast with the retention factors gained from molecular imprinting polymers, the accordant results were obtained.
