Barium isotope method for measuring cation-exchange capacity of soils and clays

Cation‐exchange capacity has been measured by isotopic exchange of 133Ba with Ba2+‐saturated soils and clays in 2·5 × 10−3 M‐BaCl2 suspensions. The rate of isotopic dilution, the efficiency of displacement of soil cations by Ba2+, and the precision of the method are critically assessed. The method i...

Zusammenfassung:	Cation‐exchange capacity has been measured by isotopic exchange of 133Ba with Ba2+‐saturated soils and clays in 2·5 × 10−3 M‐BaCl2 suspensions. The rate of isotopic dilution, the efficiency of displacement of soil cations by Ba2+, and the precision of the method are critically assessed. The method is reliable and convenient, and can be used with both buffered and unbuffered systems.
