Abstract In the two-hase water-nitrobenzene extraction system, a method for gradual separation of Cs+, Sr2+ and Ba2+ from the mixture of cations forming stable non-extractable complexes with ethylenediamine-N, N, N′,N′-tetraacetic acid in the presence of the sodium salt of dicarbollylcobaltate anion {[π-(3)-1, 2-B9C2H11]2 Co(III)}− and polyethylene glycol ligand with a mean relative molecular mass of 400 (PEG 400), respectively, was developed. In the first extraction step, Cs+ was extracted into the organic phase while the other cations studied (Ca2+, Sr2+, Ba2+, Zn2+, Co2+, Ce3+) remained in the aqueous phase. In the second extraction step, Sr2+ and Ba2+ were extracted into the nitrobenzene phase. Finally, in the following reextraction step, Sr2+ was transferred into the aqueous phase while Ba2+ remained in the organic phase.
