摘要
本文简述了荷电纳滤膜的无机物质分离特性 ,纳滤膜对离子去除的选择性较高 ,它对高价离子、阴离子、低价阳离子等具有相对较高的去除效率 ,这与纳滤膜的荷电性有直接联系 ,本文利用 Donnan效应模型和 Nerst-
Nanofiltration membrane shows intermediate characteristics between Reverse Osmosis membrane and Ultrafiltration membrane, can effectively remove organic matter with molecule weitht more than 200 Dalton. The new type of nanofiltration membrane can preserve a large part of mineral matter in effluent, while removing organic pollutants with hith efficiency, will have good market in the future.
