General Physicochemical Properties

Ion exchange membranes are characterized by many of the parameters and properties described below. Independently, the basic properties describing equilibrium and transport properties of any membrane are as follows: ion exchange capacity (molkg-1 of dried membrane), swelling (wt.% of water or other solvent), electrolyte sorption (molkg-1 of water sorbed into membrane), distribution coefficient (ratio of solute concentration in the membrane and external solution), transference number for cations and anions (determined under standard conditions), electrical conductivity (or resistivity) and salt leakage (both determined after contacting the membrane with a standard electrolyte solution).
