Anion Exchange Separation of Gallium, Indium, and Aluminum.

Ion Exchange Chromatography

“…These ions are absorbed from chloride solutions much more strongly by anion exchange resins when alcohols (143,145,172,208) or other organic solvents (98,99,141) are added.…”

Anion Exchange Separations in Hydrobromic Acid-Organic Solvent Media

“…On the basis of these observations, as well as the fact that from methanolhydrobromic acid solution only gallium and a few other elements are adsorbed on the resin, a method for the determination of gallium in bauxite samples was developed. This cannot be carried out using the separation principle earlier described by Korkisch and Kazan (4) employing acetone-and 2-methoxy-1-ethanol-hydrochloric acid media for the sequential separation of gallium, indium, and aluminum, because under these conditions the iron behaves exactly like gallium.…”

Ion Exchange Determination of Uranium in Ferrous Alloys.

“…Among these solvents, methyl glycol in particular turned out to be most suitable because of the extraordinarily high degree of adsorption of uranium from media containing this solvent and hydrochloric acid. Such a mixture has been employed previously by Korkisch and Haz an (7) to separate aluminum, gallium, and indium.…”
