A method is described for the quantitative separation and determination of uranium and beryllium in the presence of macro quantities of sodium in a ternary system of fused fluorides. The fluoride ion is volatilized as fluoboric acid during the dissolution of the dried, mixed salts with acids. Sexivalent uranium is separated from beryllium and sodium by the electrolytic deposition of the uranium as a hydrous oxide on a platinum electrode from a hot ammonium acetate solution a pH 4.0. The beryllium remains in the plating solution with the sodium, and is determined as the hydroxide. Both the uranium deposit and the beryllium hydroxide precipitate are ignited and weighed as their oxides. Finally, sodium is determined by flame photometer or calculated as the difference between the combined weights of the uranium and beryllium fluorides and the original sample weight.
