Abstract
An isotope dilution with substoichiometric separation for the determination of barium has been investigated. Barium can be extracted with a substoichi ometric amount of bis-1,2-dicarbollylcobaltate in nitrobenzene in the prese nce of 15-crown-5. It has been found that Li+, Na+, NH4+, Mg2+, Ca2+ and Fe 3+ do not interfere but the high extraction of K+ and Sr2+ ions results in marked influence.
