摘要
The use of binary extractants based on carboxilate and dialkilphosphate of the secondary and tertiary amines and their mixture for separation of ions of lanthanides (III) has been investigated. Isotherms of extraction of lanthanides nitrates (III) are linear at the initial segment, the interphase transfer of cation and anion of an inorganic salt is conjugate, lanthanides reextraction can be carried out by water. Studied binary extractanting agents are characterized by high separation factors of lanthanides. The synergetic effect for the system of di-(2-ethylhexyl)carboxylate, caprinate of di-n-octylammonium and tri-n-octylammonium has been found.
