The formation of anion rare earth element complexes with aminopolycarboxylic acids gives new possibilities for the separation of these elements on anion exchangers. The higher affinity of the Nd(dcta)- and Sm(dcta)- complexes for the anion- exchangers compared to Y(dcta)- complexes indicates the possibility of yttrium purification as a macrocomponent from the former by frontal analysis. The weakly basic polyacrylate gel anion-exchanger Amberlite IRA 68 was more effective in the purification of Y(III) from Nd(III) and Sm(III) complexes with DCTA than the strongly basic anion-exchangers of this type.
