摘要
研究了用PVA-PAN复合膜进行渗透汽化分离异丙醇/水溶液的可行性。结果表明:所用的PVA-PAN膜渗透汽化分离高浓度异丙醇/水溶液的效果较好。在本试验范围内,所用PVA-PAN复合膜的分离因子接近2 000,膜分离指数PSI值达0.8×103kg/(m2.h1),分离效果良好。
The feasibility of separating isopropanol/water mixtures by PVA-PAN composite membrane was discussed in this paper, The results showed that the property of PVA-PAN composite membrane was good for the separation of isopropanol/water under high mass fraction of isopropanol. Separation factor and permeate separation index（PSI） of the PVA-PAN composite membrane could approach 2 000 and 0.8 ×10^3 kg·m^-2·h^-1 respectively,
