On the electrokinetic properties of Ca-montmorillonite in aqueous electrolyte solutions

Experimental data on the electrophoretic mobility of Ca-montmorillonite cla y particles in electrolyte solutions at different concentrations were measu red. The values of the zeta potential are qualitatively analyzed by conside ring the structural properties of the montmorillonite particles and the typ e of anion and cation in electrolyte as well as the concentration of the el ectrolyte. When Na salts were used, the zeta potential increased with incre asing concentration.
