这是我自己翻译的 呵呵 请帮忙看一下 讨论一下 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.利用渗透蒸发分离水-乙醇混合物对聚丙烯酸聚砜复合膜,其分离特性被用于研究聚砜复合膜的复合支撑材料的制备条件和聚丙烯酸涂料中投加硝酸铝. 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.这种复合膜对水有选择渗透性,尤其用在高浓度乙醇分离水中。 The maximum separation factor was 10,800 at an ethanol feed concentration of 95 wt.%. 在质量分数为95%的乙醇溶液中,聚砜复合膜的最大分离系数可达到10800。 The membranes showed a maximum separation factor with 10 wt.% PSf in the dope solution and a 10 minute gelation time.聚砜膜最大的分离系数是在质量分数为10%的涂料溶液和胶凝时间为10分钟的溶液中。 |
