摘要:

The extraction of Ce(III) and Eu(III) by nitrobenzene solutions of bis-l,2-dicarbollylcobaltate anions in the presence of 18-crown-6 from aqueous solutions of nitric acid has been investigated. Distribution ratios, the protonization and exchange extraction constants for the investigated systems has been determined. The calculated values of distribution ratios D have been compared with experimental ones.
