| 摘 要： | 以组胺为模板分子,α-甲基丙烯酸为共功能单体,锌原卟啉为荧光功能单体,乙二醇二甲基丙烯酸酯为交联剂,合成了一种新的发光性分子印迹聚合物.通过振荡吸附后检测悬浊液荧光和柱吸附后检测流出液中组胺紫外光谱的变化,对印迹和非印迹聚合物与组胺的结合特性进行了对比.两种方法的结果一致,表明印迹聚合物对模板分子的识别选择性优于非印迹聚合物.

| Abstract: | By using histamine as the template molecule, methacrylic acid as the functional monomer, ethylene glycol dimethacrylate as the crosslinking agent, and zinc(Ⅱ)-protoporphyrin as the functional monomer, a new kind of molecularly imprinted polymer which may emit fluorescence was synthesized. Its binding property was evaluated with a batch adsorption and a column method. The results of both methods indicate that the recognition of histamine with the MIPis superior to that of the NMIP. |
