以白藜芦醇为模板分予,聚偏氟乙烯中空纤维膜为支撑体,采用自由基热聚合法制各自藜芦醇分子印迹复合膜,对膜分离性能进行了测试。结果表明,当萃取剂为纯甲醇时,物质透过膜的魁很少,印迹膜体现出对模板分子的吸附选择性;当萃取剂为0.3%冰醋酸.甲醇时,印迹膜呈现对模板分子的透过选择性。
以白藜蘆醇為模闆分予,聚偏氟乙烯中空纖維膜為支撐體,採用自由基熱聚閤法製各自藜蘆醇分子印跡複閤膜,對膜分離性能進行瞭測試。結果錶明,噹萃取劑為純甲醇時,物質透過膜的魁很少,印跡膜體現齣對模闆分子的吸附選擇性;噹萃取劑為0.3%冰醋痠.甲醇時,印跡膜呈現對模闆分子的透過選擇性。

Resveratrol molecularly composite fiber membrane (MIM) was prepared by thermal initiated free radical polymerization on the surface of PVDF hollow fiber membrane with resveratrol as template. The separation performance of the prepared membrane for resveratrol was studied. The results showed that with methanol as extract, imprinted membrane showed absorption selectivity, while the permission amounts were low. While with 0.5 % acetic acid-methanol as extract, the imprinted membrane showed permission selectivity for template.
