Adsorption Studies on Clay Minerals. VI. Alkali Ions on Attapulgite

Abstract
The exchange equilibria of the alkali ions Cs, K, Na, Li on attapulgite have been studied at 30° and 75°. Thermodynamic data for the systems have been calculated. Cesium is the most strongly adsorbed ion and the others follow in the order given. The specificity of the clay becomes lower at the higher temperature.
