dc.description.abstract电驱动条件下膜分离性能的研究对膜在微流控芯片等微小器件中的应用具有重要的指导意义.研究了界面聚合的尼龙6,6膜的电驱动分离性能,并考察了电场强度、通电时间和温度等操作条件对SO42-和Cl-离子透过性能的影响.结果表明尼龙6,6膜具有较好的SO24-和Cl-离子透过性能,并且透过性能差异不大,离子透过百分比随电场强度和通电时间的增加而增加,而随温度的增加基本保持不变.而对fITC标记的甘氨酸和赖氨酸则能完全截留,截留分子量在500左右,具有部分纳滤膜性质.该膜可望应用于微型器件中氨基酸等有机与生物大分子的电驱动分离和浓缩.
dc.description.abstractThe study of separation properties of membrane under electro-driving condition is of an important guiding significance for the application of membrane in microdevices such as microfluidic chip.The electro-driving permeation performance of SO 24- and Cl- of Nylon 6,6 membrane which was prepared by interfacial polymerization was investigated, and effects of electric field, operation time and temperature on the SO 24- and Cl- permeation performance of Nylon 6,6 membrane were studied.Experimental results showed that the permeation percentage of SO 42- and Cl- are high and similar for nylon 6,6 membrane.Ion permeation percentage was increased with electric field strength and operation time, but not changed with temperature.However, FITC labeled glycine and lysine were blocked totally, the molecular weight cutoff is around 500.So in a broader sense, the synthesized nylon 6,6 membrane is one kind of nanofiltration membrane and could be used to separate and concentrate big organic or biological molecules in miniaturized devices.
