Mixtures of dicyclohexylammonium caprylate with dicyclohexylammonium di(2-ethylhexyl) phosphate and with trioctylammonium di(2-ethylhexyl) phosphate were evaluated as synergistic binary extractants for the recovery and separation of lanthanides. Heavy lanthanides can be effectively separated from the light ones using mixtures of binary extractants based on secondary and tertiary amines.
