Abstract: The permeability of porous membrane is determined by the size of pores, membrane structure, and magnitude and character of driving forces. The value of ionic flow is predominantly governed by ionic radius and hydration radius of ions. The gradients of electric potential, osmotic as well as hydro­static pressure, and temperature work as driving forces. The permeability with respect to ions decreases with increasing diameter of membrane pores because of increasing osmotic flow of solute.
