Sorption of europium(III) and iron(III) in ionic and colloidal states on silica gel

Abstract

The sorption of europium(III) and iron(III) in colloidal and ionic states on silica gel has been studied as a function of the pH of aqueous solutions by batch equilibrations. The behaviour of Eu 3+, colloidal Eu(III), Fe 3+ and colloidal Fe(III) on the silica gel column has also been investigated. Conditions for the sorption of europium and iron from aqueous solutions are given.
