摘要
实验测定了水和乙醇在改性膜内的吸附等温线，并给出了膜的吸附选择系数；求取了水、乙醇分别与膜材料的相互作用参数，膜内溶解组成的理论值与实验值吻合良好。并考察了水－乙醇的优先扩散特征。
The sorption isotherm for the system water-ethanol-modified membrane were inverstigated.The sorption selectivity factors for water-ethanol mixture were obtained. The interaction parameters between polymer and water or ethanol were calculated. According to the interaction parameters, the theoretical sorption values presented a reasonable agreement with the experimental values. And the behaviour of water preferential Permeability during pervaporation process was also studied.
