Abstract:
The electrical conductivity, intradiffusion coefficients and ionic conductivities of sodium and caesium ions have been measured for polystyrene sulphonates in their heteroionic forms as a function of q, the number of water molecules per ionic group, at 298.15 K using a novel electrodiffusion technique. The trace diffusion coefficient and ionic conductivity of the chloride ion are also reported. The behaviour of the transport properties as a function of the water content and the ionic composition are analysed. The empirical relationships valid in homoionic sulphonic ion-exchangers hold in the heteroionic systems. Some anomalies are found in the sodium-rich region as a consequence of the formation of a lattice-like structure involving caesium ions. The counterion mobilities increase with the caesium content in the system, as found in ion-exchange membranes and electrolyte solutions. The ratio between electrical and diffusional mobilities of counterions follows the same trends observed in crosslinked ion-exchange systems and mixed electrolyte solutions, indicating that the polymer has a second-order effect.
