| 摘 要： | 采用紫外光引发原位聚合的方法制备了以聚偏氟乙烯管状微孔滤膜为支撑膜的锌离子配位分子印迹聚合物膜. 通过膜渗透实验表明, 在一定浓度锌离子存在下, 印迹膜对模板分子槲皮素表现出良好的渗透选择性. 分别考察了阳离子和阴离子对印迹膜渗透模板分子的影响. 本工作对分子印迹技术应用于实际样品中槲皮素的分离与富集具有重要意义.

| Abstract: | Using the polyvinylidene fluoride microporous membrane as the supporting membrane and zinc(II)-quercetin complex as template, the molecularly imprinted polymer membranes were synthesized through in situ polymerization by UV irradiation. The imprinted membranes exhibited selective permeation for quercetin in certain zinc(II) acetate solution through permeation binding experiment. The influences of cations and anions on the selective permeation of imprinted membranes were investigated. It will be helpful for the separation and enrichment of quercetin in herbal medicine. |
