用多元酸作交联剂与聚乙烯醇（ＰＶＡ）进行反应制得渗透汽化膜，对水－乙醇进行渗透汽化分离。研究了膜溶胀平衡过程，考察了料液组成对膜渗透汽化性能的影响。
The polybasic acid was used as crosslinking agent to react with polyvinylalcohol (PVA) to prepare pervaporation membrane, and pervaporation separation of water-ethanol. The swelling process of the membrane was studied. The influence of feed composition on the pervaporation performance of the membrane was investigated.
