Abstract
A method of preferential removal of cesium cations from aqueous solutions containing other inorganic cations. Deltahaedral heteroborane anions are added to the solution to form a salt with the cesium cations which then precipitates from the solution. The remaining dissolved Cs-deltahaedral heteroborane anion salt is then quantitatively sorbed on active charcoal to remove it from the solution.
