Porous glass membranes as model disperse systems
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.
