Abstract
Diffusion coefficients of calcium acetate, nitrate, and chloride, which characterize the transport of their aqueous solutions across porous-glass membranes with predominant pore radii of 4.5–70 nm, were determined. A decrease in the membrane pore radii is accompanied in all cases by an exponential fall of the diffusion mobility. The noticeable difference between the anion mobilities, which favors salt separation, grows with increasing radii of transport channels. In a membrane with a pore radius of 4.5 nm, the salt diffusion mobility series is changed.
