Abstract:

The results of study of selectivity of caesium sorption by a natural and surface-modified glauconite as a dependence of potassium and ammonium concentrations are presented. In the case of the surface-modified glauconite at low salt content the decrease of caesium distribution coefficients with the decrease of potassium or ammonium concentration was observed; this effect might be caused by transfer of 37 +/- 7 \% of caesium to a non-absorbable colloidal form. However, even in the worst case, values of caesium distribution coefficients for the surface-modified glauconite were as high as 10(3)-10(4) L kg(-1).
