本研究以磺化聚醚砜（SPES）为原料制备了阳离子交换膜（CEMs），并对膜的性能进行了评价。使用NaCl作为Ca2+离子上坡运输的驱动溶液，用CEM进行唐南透析实验。所制备的CEM具有与商业CEM几乎相同的离子传输性能。Donnan透析表明，进料溶液侧的Ca 2+离子浓度降低，而Na+离子浓度增加，表明Donnan透析具有潜在的分离过程，如水软化的应用。
In this study, cation exchange membranes (CEMs) were prepared using sulfonated polyether sulfone (SPES), and the characteristics of the membrane were then evaluated. Donnan dialysis experiments with the CEM were performed using NaCl as the driving solution of uphill transport of Ca2+ ions. The prepared CEM had almost the same ionic transport properties as that of a commercial CEM. The Donnan dialysis showed that the Ca2+ ion concentration on the feed solution side decreased while Na+ ions concentration increased, indicating that Donnan dialysis has a potential application for separation processes such as water softening.
