The lanthanide complexes with EDTA of the Ln(edta)^- type exhibit an unusual sequence of affinity for the polystyrene anion exchangers in the H₂edta^2- form: Sm(III) > Eu(III) > Gd(III) > Nd(III) > Pr(III) > Tb(III) > Ce(III) > Dy(III) > La(III) > Ho(III) > Y(III) > Er(III) > Sc(III) > Tm(III) > Yb(III) > Lu(III). Taking into account the position of Y(III) and Nd(III) in this affinity series, for the strongly, moderately and weakly basic macroporous anion exchangers Lewatit MonoPlus MP 500, Lewatit MonoPlus MP 64 and Lewatit MP 62 the weight (D_g) and bed (D_v) distribution coefficients of these complexes and also working (C_w) and total (C_t) ion exchange capacities were determined. Based on these values, the purifications of Y(III) from Nd(III) in the macro-micro component system on these anion exchangers were studied in the aqueous and H₂O–polar organic solvent systems. The best results of the Y(III) purification from Nd(III) were obtained using macroporous, monodisperse, moderately basic anion exchanger Lewatit MonoPlus MP 64 in the H₂O-20% (v/v) methanol system. As follows from the studies in separation of rare earth element(III) complexes with aminopolycarboxylic acids not only strongly basic gel polystyrene anion exchangers play a dominant role but also good results can be achieved using macroporous anion exchangers of this type.
