Apparent mass solvent exchange

Permselectivity real and apparent Permselectivity is a key issue when the extraction process is based on ion-exchange (31). A straightforward EQCM illustration is provided by the behaviour of PVF films upon redox switching in aqueous NaC104 solutions (22). At electrolyte concentrations below 1 mol dm 3, the normalised mass change is independent of composition, and indicates ion and solvent entry upon oxidation of neutral PVF. At higher electrolyte concentrations, permselectivity fails and salt also enters the film upon oxidation. [Pg.159]
