Trace amounts and up to 1.5 mg of gallium can be separated from up to gram amounts of Al, Cd, Cu, In, Mn, Ni, Pb, U(VI), and many other elements by eluting these elements with 8.0 M hydrochloric acid from a column containing 13.0 mL (3.0 g) of AG 50W-X4 cation-exchange resin of 100-200 mesh particle size in the H-form. Gallium can be separated from up to 2 g of iron(II) and up to 10 mg of scandium by eluting the iron with 8.0 M hydrochloric acid containing 0.30% titanium(III) chloride and eluting the scandium with 7.0 M hydrochloric acid. The retained gallium is effectively eluted with 2.5 M hydrochloric acid. Separations are sharp and quantitative. 5 figures, 3 tables.
