Notes:
Thermodynamically effective fixed-charge density of mercuric phosphate and carbonate parchment-supported membranes have been evaluated by the most recent method of Nagasawa et al., based on the thermodynamics of irreversible processes and compared with the values obtained by the Kobatake et al. and Teorell - Meyer - Sievers (TMS) methods. Bi-ionic potential (BIP) has also been measured for these membranes with three pairs of electrolyte solutions: KCl—NaCl, KCl—LiCl, and NaCl—LiCl. Theoretical values of BIP have been calculated by using the membrane potential and BIP theories recently developed by Toyoshima et al., based on nonequilibrium thermodynamics. Various parameters have also been evaluated and it was found that the theoretical equation of BIP is applicable to these parchment-supported membranes.
