Rates of alkali metal cation self-diffusion in a polystyrene sulfonate ion exchange resin and in the external solution have been measured over a range of dimethyl sulfoxide (DMSO)-water mixtures from 0 to 70 mole % DMSO. Interpretation of results is simplified by the choice of this system which exhibits relatively constant resin swelling, fairly high dielectric constant and virtually no solvent preference over the entire composition range.
The self-diffusion coefficient of Na+ in the external solution shows a moderate decrease from 0 to about 40 mole % DMSO after which it tends to level off with increasing DMSO. In …
