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...
Cation-Exchange Capacity (CEC) of Zeolitic Volcaniclastic Materials: Applicability of the Ammonium Acetate Saturation (AMAS) Method
Ammonium Acetate Saturation (AMAS) Method Ammonia Electrode Cation-Exchange Capacity (CEC) Clinoptilolite Greece Kjeldahl Ammonia Distillation
2011/12/7
Abstract: The ammonium acetate saturation (AMAS) method was used to study the cation-exchange capacity (CEC) of zeolitic volcaniclastic materials from Santorini and Polyegos Islands, Greece. The AMAS ...
