Selective salt transport of KCl over LiCl has been studied for a crosslinked poly( L ‐glutamic acid) membrane immersed in 80 vol.‐% ethanol. The permeabilities ( P s ) and solubilities were measured for various mixing ratios of the salts. The highest permselectivity ( P s (KCl)/ P s (LiCl) = 4,3) has been obtained at a LiCl mole fraction of 0,2. It is similar to that obtained in single salt systems.
