摘要:

 以不同分子量的聚乙烯亚胺(PEI)和小分子二元胺作为交联剂,对聚酰亚胺(PI)中空纤维膜进行化学交联来制备耐溶剂纳滤膜。考察了PEI分子量和交联时间对膜分离性能的影响。结果表明,膜分离性能随PEI分子量的增加变差;随交联时间的增加变好。用PEI600作为交联剂,交联时间为4h时,膜的纯水通量为0.83 Lm-2bar-1h-1,对PEG1000的截留率为97.0%。三种小分子交联剂中,用乙二胺交联膜的分离性能较好,纯水通量为2.58 Lm-2bar-1h-1,对PEG1000的截留率为82.6 %。纳滤膜对药物三七总皂苷体系有良好的分离性能。

 Polyimide hollow fiber membrane was chemicallycrosslinkedby Polyethyleneimine(PEI) of different molecular weightsand diamines in order to prepare nanofiltration(NF)membrane. The effects of molecular weightof PEI and crosslinking time on membrane separation performance were studied. It was found that membrane separation performance deteriorated with increasing molecular weightof PEI,while it meliorated with prolonged crosslinking time. Pure water permeance(PWP)and rejection of membrane was 0.83Lm-2bar-1h-1 and 97.0% respectively, when PEI600 used as crosslinking agent and crosslinking time was 4h. Membrane crosslinked by ethylenediamine obtained the best separation performance withPWPof 2.58 Lm-2bar-1h-1 and rejection of 82.6%, when separation performances of membranes crosslinked by small molecule diamines were compared. In addition, NF membrane has a soundseparation performance on the total saponins of Panaxnotoginsenosides (tSPN) system。
