這是我自己翻譯的 呵呵 請幫忙看一下 討論一下 呵呵 ![]() A PAA-PSf composite membrane was evaluated for separation of water-ethanol mixtures by pervaporation, and the separation characteristics were investigated in relation to the preparation conditions of the PSf composite support and the addition of aluminium nitrate to the PAA coating solution.利用滲透蒸發(fā)分離水-乙醇混合物對聚丙烯酸聚砜復合膜,其分離特性被用于研究聚砜復合膜的復合支撐材料的制備條件和聚丙烯酸涂料中投加硝酸鋁. The composite membrane had a water permselectivity over the entire range of ethanol feed concentrations; particularly the separation factor was high at higher ethanol concentrations.這種復合膜對水有選擇滲透性,尤其用在高濃度乙醇分離水中。 The maximum separation factor was 10,800 at an ethanol feed concentration of 95 wt.%. 在質(zhì)量分數(shù)為95%的乙醇溶液中,聚砜復合膜的最大分離系數(shù)可達到10800。 The membranes showed a maximum separation factor with 10 wt.% PSf in the dope solution and a 10 minute gelation time.聚砜膜最大的分離系數(shù)是在質(zhì)量分數(shù)為10%的涂料溶液和膠凝時間為10分鐘的溶液中。 |
