A development of the generalized Spiegler-Kedem-Katchalsky model equations for interactions of hydrated species in transport through polymeric membranes.

A new analysis is presented of the relations between multicomponent friction coefficients and hydration numbers which describe non-ionic and multicomponent solutes transport in membranes in the framework of generalized Spiegler-Kedem-Katchalsky frictional model equations. In the framework of this model the expressions linking the permeability parameters of the membrane (Lp, sigma, omegaik) with the friction coefficients (fik) for n-component non-ionic hydrated solutions were presented. This analysis is applied to calculation the frictional and phenomenological coefficients change with hydration numbers of solutes for binary and ternary non-ionic solutions was presented.
