Acceleration of the Diffusion of Aqueous CoCl_2 Solutions in Porous-Glass Membrane in the Presence of Alkali Metal Chlorides

摘要

The diffusion coefficients of a 0.1 M aqueous solution of cobalt(II) chloride in a porous-glass membrane with a predominant pore radius of 45 nm in the presence of 0.5-3.0 M of lithium,potassium,and cesium chlorides were determined.Specific features of the influence exerted by the type of accompanying electrolytes on the rate of diffusion transport of CoCl_2 were considered.
