Electrolytic transport through cylindrical etched pores in polyethylene terepthalate track-etched membrane

In the present work, electrolytic transport phenomena is studied for different electrolytes (LiCl, NaCl, KCl of different concentrations) at room temperature (25 +/- 2 degrees C) through etched pores with different diameters having cylindrical shape in track-etched membranes of polyethylene terepthalate (PET) with pore density of the order of 10(6)/cm(2). Electric potential has been used as the driving force. It has been observed that electrolytic transport through pores is different for different electrolytes, depending strongly on size of cations and is independent of size of anions. In the case of cylindrical pores, there has not been found appreciable change in forward and backward resistances.
