NOTE ON THE CAPILLARY MODEL OF TRANSPORT THROUGH CHARGED MEMBRANES

The capillary model of transport through charged membranes has been re formulated by transport equations of non-equilibrium thermodynamics. T wo geometries of pores has been considered - a capillary and a slit. I t has been assumed that the distribution of mobile components is gover ned by the zero components of forces in the plane perpendicular to the direction of transport. It has been shown that the part of transport coefficients, describing the motion of the center of mass, depends on the distribution of species inside the capillary and on the viscosity of the solution. The transport coefficients, averaged over the cross-s ection, are symmetrical.
