Method of friction coefficients determining for ternary solutions of non-electrolytes and polymeric membrane.
In this paper, the dependencies between phenomenological coefficients for membrane and friction coefficients for solutes and membrane in the framework of generalised Spiegler-Kedem-Katchalsky model for non-ionic and homogeneous solutions were presented. The matrixes of transformation from phenomenological onto frictional coefficients and from frictional onto phenomenological coefficients were worked out. Besides, the influence of hydration number of solutes on friction and phenomenological coefficients was elaborated. Moreover, the friction coefficients and their dependencies on hydration number of glucose for aqueous glucose solution (binary solution) and glucose solution in aqueous ethanol solution (ternary solution), permeating through flat polymer membrane were presented.
