Extraction of ⁸⁸Y, ¹⁵²Eu, ²²⁸Ac, ²⁴¹Am, and ²⁴⁴Cm with 2-thenoyltrifluoroacetone (TTA) resin

The behavior of ⁸⁸Y, ¹⁵²Eu, ²²⁸Ac, ²⁴¹Am, and ²⁴⁴Cm was studied with 2-thenoyltrifluoroacetone resin with batch uptake, kinetics and column studies. Studies were performed in acetate buffer solutions (pH ~ 2 to ~ 6) and there was high uptake of all isotopes, except ²²⁸Ac, at pH > 4.5. The kinetics of uptake were reasonable, although slower for the actinides, and sufficient for column studies. The retention of ⁸⁸Y, ¹⁵²Eu, and ²⁴¹Am on the resin in column studies was demonstrated as well as a reasonable separation of these isotopes from ²²⁸Ac.
