壳聚糖/聚丙烯酸聚电解质复合物膜对水/有机液体系的渗透汽化性能

Pervaporation Characteristics of Water/Organic Liquids Mixtures Through Chitosan/Polyacrylic Acid Polyelectrolyte Complex (PEC) Membrane

以壳聚糖和聚丙烯酸为原料制备了聚电解质复合物膜，并对其分离水／乙醇体系的渗透汽化特性和浓度、温度、化学组成等因素的影响进行了研究，发现后处理方法对复合物膜的分离性能影响很大。同时对其它水／有机液体系，该膜也具备优异的分离性能。

From chitosan and polyacrylic acid, the polyelectrolyte complex membranes were prepared, the pervaporation characteristics separating water/ethanol mixture and the effect of concentration, temperature, composition were also studied. The results showed that the aftertreatment methods had great influence on membrane's separation properties. The CS/PAA PEC membrane also showed excellent pervaporation characteristics using for the separation of other water/organic liquid mixtures.
