Transport of ions of one kind through thin membranes : I. General and equilibrium considerations
Abstract
The general equation for movement of ions of one kind through planar membranes and its equilibrium solutions are reviewed. A simple procedure to obtain exact numerical solutions is presented, and results are displayed as profiles of potential, field and concentration across the membrane. Finally, useful approximations for very low and very high ionic concentrations are given, and the limits of applicability of the constant-field approximation are indicated.
