A study of the interchange of hydrogen ion with various cations across polystyrene sulphonic acid ion‐exchange membranes has been made. The effects of membrane exchange capacity and crosslinking, solution concentration, temperature, counter ion valence and size on mass transfer rates were determined. The results indicated that ion and water transports across the membrane were dependent on the membrane water content, the ion concentration of the membrane, and the membrane ionic form. The mass transfer rates were relatively insensitive to change in external solution concentration.
