Abstract: | 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 (Ps) and solubilities were measured for various mixing ratios of the salts. The highest permselectivity (Ps (KCl)/Ps (LiCl) = 4,3) has been obtained at a LiCl mole fraction of 0,2. It is similar to that obtained in single salt systems. |
