P. Vanura et al., EXTRACTION OF CE(III) AND EU(III) BY NITROBENZENE SOLUTIONS OF BIS-1,2-DICARBOLLYLCOBALTATE IN THE PRESENCE OF 18-CROWN-6, Solvent extraction and ion exchange, 12(2), 1994, pp. 439-458
The extraction of Ce(III) and Eu(III) by nitrobenzene solutions of bis
-1,2-dicarbollylcobaltate anions in the presence of 18-crown-6 from aq
ueous solutions of nitric acid has been investigated. Distribution rat
ios, the protonization and exchange extraction constants for the inves
tigated systems has been determined. The calculated values of distribu
tion ratios D have been compared with experimental ones.
