Abstract

The interphase distribution of lanthanide salts in ternary aqueous–organic systems of various compositions has been studied. It has been shown that the distribution of lanthanide salts in multicomponent aqueous–organic systems differs from their distribution in extraction systems. The order of extractability of lanthanide chlorides and lanthanide nitrates in a 1 : 1 : 1 system (0.5 M NaCl (NaNO3) in water–binary extractant in hexane–isopropyl alcohol) has been determined.

Keywords:

lanthanide chlorides lanthanide nitrates multicomponent aqueous–organic two-phase systems interphase distribution separation extractability
