In: Egyptian journal of soil science 2006 v .46 (3)Summary: I N THIS WORK, the distribution of electrokinetic potential and the ditTuse particle charge (DPC) in the double layer of Ca-Bentonite towards some electrolytes CaCl2 and/or NaCl were examined. Also the effects of absolute and equivalent fraction concentrations of these electrolytes on the electrokinetic properties of Ca-Bentonite were studied. The results revealed that at low monovalent cation (NaCI) concentration; 0.01 MIL; the charges increased as Na+ ions expand the double layer and to be more diffuse with a high electrokinetic potential.
