摘要
本文报道一种由相转化法制备的荷电微孔滤膜及其制备和性能评价。采用的膜材料为聚酰胺和天然多糖。实验表明，该膜带正电荷，可以除去溶液中带负电荷的微量杂质，如细菌内在素和色素等。它属于一种新的过滤介质，在医药、纯水制备以及生物医学工程等方面有着广泛的应用前景。
The charge modified microporous membrane was prepared by using phase-inver-sion process,The membrane-making materials consisted of polyamide and natural polysaccharide.The membrane prepared was positively charged. Therefore , it was used to remove negativelycharged trace impurities from solution ,such as bacterial endotoxin ,dyestuffs. We consider that itis a new type of fiItration medium,which will find a vast application in the fields.of medicine,purewater production and biomedical engineering.
