Název v původním jazyce

Solvent extraction of europium and americium into phenyltrifluoromethyl sulfone by using synergisti mixture of hydrogen dicarbollylcobaltate and N,N,N?,N?-tetraethyl-2,6-dipicolinamide

Popis výsledku v původním jazyce

Abstract Extraction of microamounts of europium and americium by a phenyltrifluoromethyl sulfone (FS 13) solution of hydrogen dicarbollylcobaltate (H+B-) in the presence of N,N,N?,N?-tetraethyl-2,6-dipicolinamide (TEt-DPA, L) has been investigated. The equilibrium data have been explained assuming that the species HL+, HL2+ ML23+, and ML33+ (M3+= Eu3+, Am3+) are extracted into the organic phase. The values of extraction and stability constants of the cationic complex species in FS 13 saturated with water have been determined. It was found that the stability constants of the corresponding complexes EuLn3+ and AmLn3, where n = 2, 3 and L is TEtDPA, in the mentioned FS 13 medium are comparable.
