Abstract

Membrane potentials through a chemically treated cellophane membrane have been measured at different temperatures. The results have been analysed on the bases of the Kobatake equation for the membrane potential, which permits the evaluation of some parameters related to the membrane structure. The influence of temperature on these parameters has been considered. The comparison among the permselectivity and electrical resistance values obtained at 25 °C with an untreated and two treated cellophane membranes, one chemically treated and another annealed, show a more significant loss of selectivity for the chemically treated membrane than for the annealed one, which can be attributed to a higher influence of the chemical treatment on the cellophane membrane structure than that due to the heating.
