SEPARATION OF BARIUM(II) FROM STRONTIUM(II) BY MEANS OF THE SOLVENT EXTRACTION WITH DIBENZO-24-CROWN-8

Abstract Barium(II) (3.00×10−4 M) was easily separated from strontium(II) (3.00×10−4–1.70×10−2 M) by means of the solvent extraction procedure with a nitrobenzene solution of dibenzo-24-crown-8. Average recovery of barium(II) was 97% and only 10−3 part of the strontium(II) in the initial sample solution was recovered.
