Actinoid separations by extraction chromatography
Two separation methods based on extraction chromatography are presented: the first for the determination of Pu and Am, and the second for U and Th. These two methods are applied to (i) the determination of Pu and Am in diluted MOX samples and (ii) the analyses of Th from four standard solutions. Both of the methods gave high recoveries and showed good reproducibility for Th, Pu and Am. Special requirements for the determination of Th are discussed.
