Sorption behavior of cesium and strontium ions on mixtures of clay sorbents

Abstract

The sorption behavior of Cs and Sr ions on natural clay minerals such as sand, bentonite and loam, and mixtures of bentonite-sand and -loam was studied under static condition. It was found that the distribution ratio of Sr ion on bentonite and loam are influenced by H ion concentration of solution, along with the concentration of ion of interest. The obtained results revealed that the distribution ratio of ion on the clay mixture can be expressed in terms of distribution ratio of each constituent of the mixed sorbent, provided that the corrections for pH and sorbed ion concentration of solution are made. © 1989 Taylor & Francis Group, LLC.
