THE SEPARATION OF CLAY MINERALS BY CONTINUOUS PARTICLE ELECTROPHORESIS

A BECKMAN CONTINUOUS PARTICLE ELECTROPHORESIS SYSTEM IS CAPABLE OF SEPARATING MIXTURES OF KAOLINITE AND MONTMORILLONITE INTO FIVE OR MORE FRACTIONS BY ONE PASS THROUGH THE INSTRUMENT. THE LOWEST AND HIGHEST MOBILITY FRACTIONS OBTAINED FROM A 50:50 ARTIFICAL MIXTURE OF THESE CLAYS CONTAIN, RESPECTIVELY, 85 PERCENT MONTMORILLONITE/15 PERCENT KAOLINITE, AND 5 PERCENT MONTMORILLONITE/95 PERCENT KAOLINITE. THE INTERMEDIATE FRACTIONS CONTAIN VARYING PROPORTIONS OF THE TWO MINERALS. MIXTURES OF CLAYS IN RECENT SEDIMENTS CAN ALSO BE SEPARATED, BUT NOT AS EFFECTIVELY AS ARTIFICIAL MIXTURES. THE MOST COMPLETE SEPARATION WAS OBTAINED IN A -40,000 MOLAL SODIUM CARBONATE BUFFER CONTAINING 5 PERCENT ETHYLENE GLYCOL AT PH 10. /AUTHOR/
