Study of the Exchange Characteristics of Montmorillonite Clay for Fission Product Cations for use in the Generation of Insoluble Aerosols

摘要

The exchange of cesium, cerium, strontium and yttrium with exchangeable ions in montmorillonite clay in aqueous suspension has been studied. The percent of the initial ion concentration exchanged into the clay has been determined as a function of the initial concentration. This data is useful in the preparation of clay having a high specific activity. It was found that clay can be prepared which has a specific activity of 2 mCi per mg for 137 Cs and 6 mCi per mg for 91Y and 144Ge.
