The time-dependent theoretical solution to ionic mass transport through a uniform membrane under the influence of a uniform electric field is derived. Equivalent lag times and steady-state fluxes are then determined. The enhancement ratio of ionic flow (at a given voltage) to passive flow is shown to be proportional to the voltage for large augmenting voltages, and to decrease exponentially for large retarding voltages. Positive enhancement factors can be as large as 120 for triply charged ions, with one volt imposed across a membrane. The lag times decrease with increasing voltage magnitudes, and can (for triply charged ions, with one volt imposed across a membrane) be as small as 1/20 of the passive lag time. |
