Correlation between Cation Exchange Capacity and Geotechnical Properties of Lateritic Soils.
Cation exchange as influenced by the type of cations in different clay minerals
Cation exchange influenced type cations different clay minerals
2012/3/30
Physical and chemical properties of most soils are influenced by their ion-exchange characteristics, including the amount and balance of individual ions present (Rayment and Lyons, 2011). Cation Excha...
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...
