Mass transport through charge-micromosaic membranes

Electrolyte and water fluxes were measured through a charge-micromosaic membrane of which the length of a repeating cation- and anion-exchange unit was 50 to 100 nm. The overall transport number of K + ions in the membrane was about 0.5 at KCl solutions of 10 ±6 to 10 −3 mol-cm −3. The stagnant laye...

Summary:Electrolyte and water fluxes were measured through a charge-micromosaic membrane of which the length of a repeating cation- and anion-exchange unit was 50 to 100 nm. The overall transport number of K + ions in the membrane was about 0.5 at KCl solutions of 10 ±6 to 10 −3 mol-cm −3. The stagnant layers on both sides of the membrane played an important role in electrolyte transport. Negative osmosis or negative reflection coefficients were observed through the membrane for KCl, NaCl, and LiCl solutions of 10 −6 to 3 x 10 −4 mol-cm −3.
