A systematic study of the absorbabilities of cations with AG 50W-XS resin in hydrochloric and nitric acids indicated that the difference in the equilibrium distribution coefficients among beryllium and a number of other cations is large enough to warrant a good separation. This fact was used to develop a cation exchange chromatographic procedure for the separation of Be from Al(lII), Fe(III), Y(III), and Ce(IlI). Other elements that are completely separated include Sr(II), Ba(II), Ga(III), La(IlI), and the rare earths, Zr(IV) and Th(IV). A number of elements, such as Cd(II), Sn(IV), S(IV), Hg(II), V(V), Mo(V), Au(III), As(III), and Sb(III), can be eluted from the column with 0.5N HCl before the separation of beryllium from the more strongly absorbed elements is started. The method of separation is applied to the determination of beryllium in a gadolinite ore.
