Using several asymmetric cellulose acetate membranes (CA), transport parameters such as the hydrodynamic (%p) and osmotic (Β£~) permeability and the asymptotic solute rejection (r) were determined from hyperfiltration experiments at 29C with different brine solutions (0.i M and 0.5 M NaCI, 0.i M NAN0
The distribution in cellulose acetate (CA) membranes of a solution of two electrolytes with a common anion has been studied. The system composed of a generic acid H An and a generic symmetric salt MeAn has been studied and a theoretical mod& based on Donnan and dielectric exclusion phenp!ena has be
