塑化剂类双模板分子印迹聚合物的制备及其性能研究
Study on the Preparation and Characterization of Dual Template Molecularly Imprinted Polymer as a Plasticizer
摘 要
以表面接枝乙烯基的硅胶为载体,邻苯二甲酸二甲酯和邻苯二甲酸二丁酯为模板分子,甲基丙烯酸为功能单体,二甲基丙烯酸乙二醇酯为交联剂,制备了分子印迹聚合物,分析了聚合物的吸附行为。结果表明:印迹聚合物存在着两类不同结合位点,吸附过程为多分子层吸附。将该印迹聚合物作为固相萃取分离的固定相,并与高效液相色谱检测技术相结合,可对被塑料瓶所污染而存在于所盛装的饮料中的塑化剂进行有效的分离和富集。

Abstract
A molecularly imprinted polymer (MIP) was synthesized by using silica gel, with vinyl group linked on its surface, as carrier, dimethyl phthalate and dibutyl phthalate as template molecules, methacrylic acid as functional monomer and ethylene dimethacrylate as crosslinker. The adsorption behavior was studied, and as shown by the results that there were two types of binding sites on the surface of MIP and its adsorption process was a multi-molecular layer adsorption. The MIP prepared was applied to SPE as the stationary phase and proved to have effective separation and enrichment capacity as combined with the HPLC determination of plasticizer present in beverage as pollutant origniated from the plastic container.
