Abstract

The free solvent transport number in an MF-4SK perfluorinated membrane in solutions of alkaline metal chlorides and hydrochloric acid is for the first time calculated within the framework of a capillary model based on the data of standard contact porosimetry and membrane conductometry. The reasons for the change in the structural characteristics and specific conductivity upon varying the nature of the counterion are discussed. The portion of through mesopores in MF-4SK homogeneous and MK-40 heterogeneous sulfonated cation-exchange membranes is estimated using the experimental data on the water transport numbers in solutions of electrolytes of different natures.

反离子性质对磺化阳离子交换膜电渗透输水影响的实验与理论研究

基于标准接触孔隙率法和膜电导率法的数据，首次在毛细管模型的框架内计算了MF-4SK全氟膜在碱性金属氯化物和盐酸溶液中的自由溶剂输运数。讨论了结构特性和电导率随反离子性质的变化而变化的原因。利用不同性质电解质溶液中水输运数的实验数据，估计了MF-4SK均相和MK-40非均相磺化阳离子交换膜中穿透介孔的比例。
