چکیده انگلیسی
The structural, adsorption and electrokinetic characteristics of porous glass (PG) membranes, prepared by leaching of various alkali borosilicate glasses, were studied as a function of pH in the presence of 1:1, 2:1 and 3:1 electrolytes. The obtained experimental results were used to calculate both of surface reaction constants and ion adsorption potentials within the framework of a 2-pK model. The electrochemical parameters of membranes (counterion transport numbers, ion concentrations and mobilities in the pore space, Donnan potentials) were also calculated within the framework of a homogeneous model. The dependencies of membrane characteristics on the electrokinetic radius were analysed.
