Název v původním jazyce

Solvent extraction of europium and americium into phenyltrifluoromethyl sulfone by using synergistic mixture of hydrogen dicarbollylcobaltate and ?classical? CMPO

Popis výsledku v původním jazyce

Extraction of microamounts of europium and americium by a phenyltrifluoromethyl sulfone (FS 13) solution of hydrogen dicarbollylcobaltate (H+B-) in the presence of octyl-phenyl-N,N-diisobutylcarbamoylmethyl phosphine oxide (?classical? CMPO, L) has beeninvestigated. The equilibrium data have been explained assuming that the complexes HL+, HL+, ML23+, ML33+, and ML43+ (M3+ = Eu3+, Am3+) are extracted into the organic phase. The values of extraction and stability constants of the cationic complex speciesin 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, 4 and L is ?classical? CMPO, in water-saturated FS 13 are comparable.
