The linear polyether, 1, 13-bis-(8-quinolyl)-1,4,7,10,13-pentaoxatridecane (K-5), has been shown to enhance the extraction of americium (Am(III)), curium (Cm(III)), and europium (Eu(III)) by thenoyltrifluoracetone (hTTA). The extraction of the trivalent metals from an aqueous acetate buffer system (pH = 4.8) into HTTA/chloroform at 25/sup 0/C was studied as a function of the concentration of K-5 in the organic phase. The synergistic specie was determined to be M(TTA)/sub 3/ K-5 and organic phase stability constants for the formation of this complex were evaluated. The results of this study indicate that K-5 has the ability to show some size selectivity for the trivalent metal ion. 3 figures, 3 tables.
