Abstract
In partition equilibria of Ca2+ , K+ and Cl- between a swollen charged membrane and an aqueous bath of mixed KCl and CaCl2 electrolytes, the equilibrium concentration of the bivalent ion in the membrane decreas es to a minimum value as its concentration in the bath increases. The value of the concentration minimum decreases with increasing KCl : CaC l2 concentration ratio in the bath. Simulations and analysis have been performed on the basis of Donnan distribution theory.
