Abstract
The equations that describe the macroscopic transport of a solution containing a binary electrolyte through a semi-permeable membrane are derived following the approach of the Thermodynamics of Irreversible Processes. This approach for the description of the macroscopic transport of the solution doesn't provide any physical interpretation of the phenomena involved. As a result, a macroscopic transport model able to provide a physical interpretation of the phenomenological parameters is proposed. Such a model is able to explain the dependency, observed in laboratory experiments, of the chemico-osmotic efficiency coefficient, ω, on the solute concentration, Cs, and to explain the dependency of the other experimental parameters on ω.
