Abstract:

The solvent extraction behavior of scandium, yttrium, and a number of rare earth metals was investigated. Pure 2,2,6 tetramethyl 3,5 heptanedione, hereafter referred to as Hthd, was used as the chelating agent and the organic solvent. In addition, the closely related reagent, 1,1,1-trifluoro-5 5-dimethyl 2,4-hexanedione, hereafter referred to as Kfdhd, was studied as a reagent for separating europium and terbium by countercurrent distribution extractions. Atomic absorption as a method of analysis for the rare earths was also investigated. Author
