Abstract

The ion-exchange characteristics of the clinoptilolite rock in China for alkali metal ions

and the relations between the static exchange capacities and the radii of alkali metal ions have been studied. Under dynamic condition

the selective coeffients of the systems K+/Rb+

K+/Cs+and Rb+/Cs+were determined

and the separating properties of the system K+/Rb+/Cs+were investigated. Our studies reveal that it is possible to extract alkali metal ions by using clinoptilolite rock. We have also studied the separating conditions of K+

Rb+and Cs+in the concentrated salt solution of alkali metal produced in a factory. The results show that this clinoptilolite rock has good extracting characteristics and efficiency for alkali metal ions

and the technological process extracting rubidium salts and cesium salts has been worked out under experimental conditions.
