Abstract
The separation of lanthanide (III) ions with binary extractants based on carboxylates, di-(2-ethylhexyl) phosphates of secondary and tertiary amines and their mixtures has been studied. The parameters of lanthanide nitrates extraction from the aqueous phase by solutions of these substances in nonpolar diluents have been found to fit the binary extraction mechanism. For systems containing di-(2-ethylhexyl) phosphate and caprate of dioctylammonium and trioctylammonium, synergistic effects have been observed.
