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