1953 A. G. Winger et al. in Jrnl. Electrochem. Soc. 100 178/2 For the purpose of this paper, an ideal permselective membrane will be defined to be a membrane which, when subjected to a potential gradient, permits passage of cations to the exclusion of anions, or vice versa.

1969 W. R. R. Park Plastics Film Technol. viii. 197 A process which may come to have the universal utility of distillation is the use of permselective membranes for the separation of mixtures of liquids or gases.

1994 Science 1 Apr. 50/2 The polymer films can function as permselective membranes, allowing the penetration of specific anions or cations.

2002 Amer. Jrnl. Pathol. 161 2179 Enhanced passage of plasma proteins across the glomerular capillary barrier because of impaired permselective function.

1953 A. G. Winger et al. in Jrnl. Electrochem. Soc. 100 179/1 In any electrolytic process ion concentrations are appreciable and perfect permselectivity is an idealized situation of little practical interest.

1962 S. B. Tuwiner Diffusion & Membrane Technol. ix. 177 The most important factor which affects permselectivity for a given membrane is the concentration of the electrolyte.
