Vm. Barragan et al., EFFECT OF UNSTIRRED SOLUTION LAYERS ON ELECTROOSMOTIC PERMEABILITY OFCATION-EXCHANGE MEMBRANES, Journal of colloid and interface science, 168(2), 1994, pp. 458-464
Electro-osmotic fluxes of water through two cation-exchange membranes
have been measured under different experimental conditions. The influe
nce of unstirred solution layers adjoining the membrane surfaces on th
e obtained values has been studied both theoretically and experimental
ly A model has been developed which gives quantitative information abo
ut the concentration polarization effects on the electro-osmotic fluxe
s. The theoretical predictions are compared to the experimental result
s, and the accordance may be considered satisfactory. (C) 1994 Academi
