Abstract

The Kedem-Katchalsky phenomenological coefficients Lp, LD and LpD of albumin transport through PVA membranes were calculated through knowledge of the corresponding multicomponent diffusion coefficients. Non-equilibrium thermodynamic considerations for non-ideal systems of hydrophilic solutes in water were used to describe the transport of albumin through swollen non-porous (gel) polymeric membranes. Experimental results and the effect of polymer structure are also discussed.
