The elements lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium were eluted by perchloric and hydrochloric acid of different strengths from columns of di-(2ethylhexyl) orthophosphoric acid retained on a poly-(vinyl chloride/vinyl acetate) copolymer. From the results separation factors were calculated and were compared with values obtained from solvent extraction determinations with the alkyl-phosphoric acid dissolved in toluene. (auth)
