摘要
研究了UPANA-1复合超滤膜分离性能,以及压力、时间、进样浓度等操作条件对UPANA-1膜性能的影响.同时研究了UPANA-1复合膜的抗污染情况及其膜表面微观状态.结果表明:(1)UPANA-1复合超滤膜的截留相对分子质量为1000;(2)操作压力的提高、运行时间的延长和溶液浓度的变化对UPANA-1复合超滤膜的截留率影响较小;(3)与基膜相比,UPANA-1复合膜的耐污染性有大幅度的提高.
Separation performance of UPANA-1 membrane and effects of such operating conditions as pressure,time,concentration of solution,etc.on the performance of membrane were studied.At the same time,the resistance ability to contamination and the fine structure of UPANA-1 membrane surface were preliminarily studied.Results showed that:(1) the MWCO of UPANA-1 membrane was 1 000;(2) increase in operating pressure,extension of operation time and change in solution concentration have little effect on the rejection of membrane;(3) compared with the substrate PES membrane,UPANA-1 membrane's resistance to contamination of was largely improved.
