摘要：

In this article we establish a steady-state theoretical model for cotransport through liquid membranes. Integration of the flux equation gives the concentration in the receiving phase as a linear function of time under certain conditions. From this, an expression for the relative permeability of the carrier-permeant complex with respect to the carrier is obtained; this permeability depends on the equilibrium constant of the interphases reaction and on another parameter related to the initial concentration of permeant in extramembrane phases. An experimental study of the variation of permeant concentration in the receiving phase allows determination of several characteristic transport parameters. © 1990, Taylor & Francis Group, LLC.
