Permselectivity in a Chlor-Alkali Cell

Interpretation of Permselectivity as a Function of Membrane Properties and Cell Parameters [Pg.475]

Several approaches to the understanding of membrane permselectivity can be taken these include the use of the Nernst-Planck transport equations, irreversible thermodynamics, and [Pg.475]

Several new developments in interpreting the transport properties, based on the structural parameters, have been reported by Koh [Pg.476]

Mauritz and co-workersand Hopfinger have reported spectroscopic and sorption studies of perfluorosulfonate membranes. Several conclusions drawn in these studies are useful in the interpretation of current efficiencies as a function of caustic solution concentration. Sorption measurements of an 1100-EW film in equilibrium with NaOH solutions from 7.5 to 18 M show that the [Pg.477]

An important question is why the perfluorinated carboxylate polymer presents a much more effective barrier to hydroxide ion transport compared to the sulfonate analogue, for any caustic concentration used. There may be several factors involved. First, a more complete phase separation of the ion-clustered regions for [Pg.478]
