摘　　要：用γ-(甲基丙烯酰氧)丙基三甲氧基硅烷修饰的微粒硅胶作基质,以甲基丙烯酸(MAA)为功能单体,奎宁为模板,制备得到一种新型的硅胶表面键合分子烙印聚合物(M IP),用红外光谱对聚合物进行了表征;用荧光发射光谱和紫外光谱预测了奎宁分子与MAA相互作用形成的超分子复合物;通过平衡吸附实验评价了所制备聚合物的吸附性能,结果显示,模板聚合物与空白聚合物有较大差异,对模板最大特异性吸附量值为36.4μmol/g,对奎宁与辛可宁的分离因子α达到1.64。With micro-porous silica functioned with 3-（trimethoxysilyl） propyl methacrylate reagent as camer, a kind of novel molecularly imprinted polymer bound on silica surface was synthesized by using MAA and quinine as functional monomer and template respectively. The polymer was characterized by IR and SEM. MAA and quinine could interact to form super-molecular complexes, which were confirmed by fluorescence and UV spectroscopy. The adsorption properties of the polymers toward substrates were evaluated by equilibrium adsorptive experiments. The results show that there exist distinct difference between the template polymer and the control polymer, the maximum special adsorption amount toward template is 36. 40 μmol/g. The separation factor reaches 1.64 for quinine and cinchonine.
