摘    要：用自制聚乙烯醇-壳聚糖共混复合膜分离乙醇-水溶液,考察了料液浓度、温度和流速等因素对渗透汽化过程的影响,提出了膜分离过程特性关联式.

Abstract: The ethanol-water mixture was separated by pervaporation through polyvinyl alcohol-chitosan blended composite membrane, and the influence of the operation conditions, such as feed concentration,temperature and feed circulating velocity, on the above process was studied. The empirical membrane characteristic prediction formula has also been provided in this work.
