ABSTRACT
In the case of the diaphragm cell transport equation where the interdiffusion coefficient is a function of concentration, we have derived an integral of the form, t=B0+BL ln(Δc)+B1(Δc)+B2(Δc)2+..., where t is the time and Δc is the concentration difference across the frit. The coefficient, B0, is a constant of integration, while the coefficients, BL,B1,B2,..., depend in general upon the cell constant, the compartment volumes, and the interdiffusion coefficient and various of its concentration derivatives evaluated at the mean concentration for the cell. Explicit formulas for BL,B1,B2,... are given.
