摘要

对交联聚乙烯醇均质膜于全浓度范围的乙二醇／水溶液中分别在60、70和80℃下进行了溶胀平衡实验研究.基于改进的UNIQUAC方程和Flory-Huggins热力学理论，建立了液-膜两相溶胀平衡模型方程，并用该模型方程计算出了水和乙二醇分子在交联聚乙烯醇均质膜中的溶解平衡浓度，其计算结果与实验值吻合良好.

Abstract

The swelling equilibrium for the system water－ethylene glycol-crosslinked PVA at various temperatures were experimentally investigated.A liquid-membrane swelling equilibrium model was developed on the basis of modified UNIQUAC equation and Flory-Huggins thermodynamics and good agreement between the derived equation predictions and the experimental values for the preferential sorption of water-ethylene glycol mixture in the crosslinked PVA membrane was obtained.
