The zeta-potential of montmorillonite-water colloid systems of different districts and distinct types are different. In this study the zeta-potentials were determined for montmorillonitewater colloid system of different districts and types. The relationship of octahedral(Fe~(3+)+Mg~(2+)) and the cell parameter b0 dimension of montmorillonites with the zeta-potential of montmo rillonite-water colloid systems were discussed.

Key words: Montmorillonite, Electrophoretic mobility, Hydrated film, Cell parameter
