Representative elution profiles of terbium and gadolinium from DGA column using 0.05 M HCl (a), from Sykam column using 0.13 M and 1 M α-HIBA (b) and from LN3 column using 0.01 M HCl and 0.05 M HCl (c). In this set of experiments, the columns were loaded with lanthanide metal tracers, which were subsequently eluted with the eluents mentioned. The sample aliquots were measured by means of ICP-OES.
