摘要
介绍了纳滤膜及其特点,研究了采用自制的中空纤维纳滤膜(NFm)对苦咸水中部分物质的去除情况。实验表明,所制备的纳滤膜能有效截留二价和多价阳离子,对单价阳离子的截留率极低。纳滤膜对阴离子的截留率按下列顺序递增:Cl-,NO3-,SO42-,并能部分去除水中的F-。
Nanofiltration membrane（NFm） and its characteristics were introduced.The explusion of some substance from saline water were studied adopting self-made hollow fiber nanofihration membrane.The result showed that bivalent and multivalent cations could be removed effectively,while the rejection of univalent cations was very low.The rejection of anion using nanofihration memebrane increased progressively in following order：Cl^-,NO3^-,SO2^- and F^- could be removed partly.
