A METHOD FOR THE DETERMINATION OF THE CATION EXCHANGE CAPACITY OF CLAY MINERALS AND SOILS
CLAY MINERALS SOILS METHOD
2011/11/15
For many purposes it is desirable to have a method for the determination of the cation exchange capacity of clay minerals based on principles as free from ambiguity as possible. Most of the many metho...
VISCOSITY STUDIES ON DILUTE CLAY MINERAL SUSPENSIONS
CLAY MINERAL SUSPENSIONS VISCOSITY STUDIES
2011/11/15
A technique has been developed for obtaining reproducible viscometric data on dilute clay suspensions using the recently developed capillary viscometer of Maron, Krieger and Sisko. Aging and type of m...
The clay minerals, generally characterized by their small particle size, affinity for water, and response to chemical changes in their environment, are noted for their gelling and viscoslty-increasing...
It has been demonstrated that ferric iron is the principal source of the oxidizing action of the surface of attapulgite clay. The extent of oxidizing action in a- given time (the oxidizing power) has ...
