以槲皮素-钴(Ⅱ)的配合物为模板分子,在强极性甲醇溶剂中分别采用低温光引发和高温热引发聚合制备槲皮素-钴(Ⅱ)配位印迹聚合物.紫外-可见光谱分析确定了槲皮素与钴(Ⅱ)形成配合物的最佳配位比.根据印迹聚合物的平衡结合量优化功能单体丙烯酰胺用量.利用红外光谱、透射电镜和平衡结合实验,考察不同引发方式对聚合物的结构、微观形貌及结合性能的影响.进一步通过特异吸附容量和印迹指数确定,低温光引发聚合更适于配位分子印迹聚合物的制备.同时研究了不同阳、阴离子对印迹聚合物选择识别性的影响.结果表明光引发的金属配位分子印迹聚合物具有良好的吸附选择性,印迹指数可达3.919.
Quercetin - cobalt (Ⅱ) complexes were used as template molecules to prepare quercetin - cobalt (Ⅱ) coordination imprinted polymers by low temperature photoinitiation and high temperature thermal polymerization in strongly polar methanol solvent respectively. UV - The best coordination ratio of quercetin and cobalt (Ⅱ) complexes was determined by visible spectroscopy. The amount of functional acrylamide was optimized according to the amount of equilibrium binding of the imprinted polymer. Using infrared spectroscopy, transmission electron microscopy and equilibrium binding experiments, The effects of different initiation methods on the structure, morphology and bonding properties of the polymers were also investigated.Furthermore, through the determination of specific adsorption capacity and imprinting index, low temperature photoinitiated polymerization is more suitable for the preparation of coordination polymer.In addition, , And the effect of anions on the selective recognition of the imprinted polymer.The results show that the photoinduced metal coordination polymer imprinted polymer has good adsorption selectivity and the imprinting index can reach 3.919.
