| 摘 要： | 以茶碱作为模板分子,通过对硅胶表面进行修饰后进行接枝共聚,制备了基于硅胶表面修饰的分子印迹聚合物.借助红外,元素分析,电镜等表征方法对聚合物的制备进行了评价和探讨.用紫外分光光度法考察了分子印迹聚合物对茶碱的吸附特性.实验表明这种分子印迹聚合物对茶碱表现了特异性吸附,而对相似化合物咖啡因则无吸附,并用薄层色谱对聚合物的分离性能进行了研究.

| Abstract: | Silica particles were modified with polymerizable double bonds on the surface.Then the molecular imprinting polymer imprinted with theophylline was grafted to the surface of modified silica.The molecularly imprinted polymer(MIP) based on the surface of silica was characterized by IR,element analysis(EA),and scanning electron microscopy(SEM).The adsorption of theaphylline by MIP was mearsured.The sepeartion property of MIP toward theaphylline and caffeine was investigated by thin layer chromatography(TLC). |
