Abstract:

THE EXTRACTION OF SALICYLATES OF Sc, Y, Ce La, U AND Th The distribution of salicylates of Sc, Y, Ce, La, U, and Th between isoamyl alcohol andAQUEOUS SOLUTIONS DEPENDS ON THE PH of the medium. Salicylates of Sc, Y, Ce, La, Th and U are quantitatively extracted by isoamyl alcohol at a pH of 3.3 to 5.5 for Sc, greater than 4 for Y, greater than 4.5 for La, greater than 5.0 for Ce, greater than 3.0 for Th, and between 2.5 to 5.5 for U. THE FORMATION OF COMPLEX COMPOUNDS OF Nd AND Y WITH ETHYLENEDIAMINATETRAACETIC ACID WITH CATION-EXCHANGING CHROMATOGRAPHY The mechanism of the formation of complex compounds of Nd and Y with ethylenediaminetetraacetic acid during cation exchange chromatography was investigated. During elution of Nd by a solution of salts of H4Y there occurs an absorption of H4Y by the resin, apparently in the form of a complex compound Nd NdY3. A noticeable absorption of H4Y does not occur during elution of Y. The difference in the ability of the complex compounds Nd3 and Y3 with H4Y to be absorbed by the resin can further the division of the rare earths.
