AbstractThe permeability behavior of potassium chloride through cellophane grafted with acrylic acid by a γ‐irradiation method was studied by the theoretical equation derived from the phenomenological equation and compared with the results of Donnan membranes equilibrium. It was shown that the permeation of potassium chloride through the grafted cellophanes exhibited behavior typical of a polyionic membrane for grafts of more than 55 but depended on the permeability of both cellophane and graft regions for lower percents of grafting. It was found that the dominant factor affecting the permeation of potassium chloride was an effective concentration of fixed charge in the membra
