摘　　要：采用分子印迹技术,以对羟基苯乙酮为模板分子,丙烯酰胺为功能单体,乙二醇二甲基丙烯酸酯为交联剂,合成了对模板分子对羟基苯乙酮具有良好选择性的印迹聚合物。通过静态平衡结合法以及Scatchard分析法研究了该聚合物的结合能力和选择性能。结果表明,该印迹聚合物平衡离解常数Kd=0.415 mmol/L,最大表观结合量Qm ax=144.79μmol/g。红外光谱研究表明聚合物中存在着与模板分子相互作用的特征基团。A molecularly imprinted polymer possessed highly selective for p-hydroxyacetophenone was prepared by molecular imprinting technique with acrylamide （AM） as the function monomer and ethylene glycol dimethacrylate（EDMA） as the cross linker. The binding characteristics and recognition ability of the molecularly imprinted polymer（MIP） were studied by static adsorption equilibrium method and Scatchard analysis. The results showed that the dissociation constant （Kd） and the maximum apparent binding capacity（Q ） were 0. 415 mmoL/L and 144.79 μmoL/g, respectively. The infrared spectrum of the polymer further indicated that there were some characteristic groups in the molecularly imprinted polymer which eould interact with the template.
