Anion Exchange Separation of Beryllium

Anion Exchange Separation of Gallium, Indium, and Aluminum.

“…Ion exchange coupled with mixed solvent elution techniques has proved to be successful as a general separation method. Both anion and cation exchange resins combined with various alcohol or acetone solutions of mineral acids as solvents have been employed for the separation of transition elements (1, 6, 20), U and Th (11-13), the rare earths (3,4,16), and Group I and II elements (5,7,8,19).…”

Hydroxyazo compounds as reagents for beryllium

“…Separation of beryllium from interfering ions does not seem to present too great a problem. A recent correspondence (36) in Analytical Chemistry suggests an anion exchange separ ation of beryllium from virtually all other cations having an ionic radius greater than that of beryllium using a 90 percent isopropanol-10 percent ôîT-hydrochloric acid medium eluent.…”
