Abstract Radium can be separated from barium-radium mixtures in ratios as high as 4440to 1 by a single elution from a cation exchange resin. Bariuim elution characteristics from Dowex 50 resin, position of elution maxima, and maximum barium loadings are correlated with citrate concentration and pH by the use of citrate complex equilibria, Ammonium citrate, 0.32M at pH 5.6, is the most satisiactory uluen; of those used; from the standpoints of separation factor and freedom from precipitation in the column. Conditions affecting the precipitation of slightly soluble barium citrate during elution with ammonium citrate sre discussed. Eluting above 25 C decreases separation factors and permissible barium levels.
