The adsorption behavior of cesium on pure minerals is reviewed. Althou
gh this field has been investigated intensively, the data arc extremel
y variable in scope and interpretation with detailed information being
available for only a few minerals. In current investigations in this
field, the emphasis is on the nature of the adsorption sites and ident
ification of these sites using spectroscopic techniques. In the first
section of this review, the general mechanism of cesium adsorption is
discussed and this is followed by consideration of the effect of param
eters such as cesium concentration, the properties of the mineral and
the characteristics of the solution phase, on cesium adsorption. Final
ly, interaction of cesium with some different minerals is described in
some detail.
