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.

The possibility of removing rare earth element(III) nitrate complexes selectively from the 90% v/v C2H5OH–10% v/v 7 M HNO3 system on Wofatit SBW × 6% DVB was examined. Weight and bed distribution coefficients were determined from the breakthrough curves of individual rare earth elements. Based on these, the affinity series of rare earth element nitrate complexes in this system was determined. The effect of crosslinking the anion exchanger Wofatit SBW × 2%, 4%, 6%, 8%, 12% and 16% DVB on the sorption of rare earth element nitrate complexes in the 90% v/v C2H5OH–10% v/v 7 M HNO3 system was also investigated.
