Abstract : Ion flux is considered across a membrane containing wide pores and separating 2 concentrations of a single salt. A formula for cation flux is derived for electro-diffusion and convection in the cases where forces present are due to (1) the concentration gradient, (2) the transmembrane potential gradient, and (3) the linear bulk flow velocity (V) through the membrane pores. The formula is valid whether the water streaming V is induced by a hydrostatic or an electroosmotic pressure difference across the membrane. (Author)
