  1. Through the flux / retention experiments it was shown that when the applied pressure rises, both volume flux and rejection increase, too ; and that the higher the feed salt concentration, the lower rejection and volume flux. the charged mosaic membranes could permeate mono - valent and bi - valent inorganic salts, but reject the low - molecular - weight organics. furthermore, sem was used to observe the surface and the cross section of the composite membrane

    另外,膜性能表徵結果顯示:隨著操作壓力的增加,膜通量及膜對電解質的截留率均趨增加;而隨著原料液濃度的增加,通量和截留率都有所降低;膜對低分子有機物和無機電解質混合體系(如:亞硝基紅鹽與naci混合體系;蔗糖與nazso ;混合體系等)的選擇性較高,能實現其有效分離。
