摘要：

The influence of the salt concentration (c(0)), the diffusion boundary layers, and the ratio of the counter-ions diffusion coefficients on the bi-ionic potential (BIP) values have been analysed theoretically on the basis of a simple mathematical model based on the Nernst-Planck equations and on the TMS model. For c(0) < 0.1 M, the numerical solution of the boundary-value problem for an ideal permselective membrane gives a theoretical BIP vs c(0) curves similar to those obtained experimentally by Dammak ct al. The diffusion coefficient ratio in the membrane plays an important role in determining the BIP values. (C) 1997 Elsevier Science Ltd.
