Abstract
The isotope dilution with substoichiometric separation for the determi nation of strontium has been investigated. Strontium can be extracted with a substoichiometric amount of bis-1,2-dicarbollylcobaltate in nit robenzene in the presence of 15-crown-5. It has been found, that Li+, Mg2+, Ca2+ and Fe3+ do not interfere in the strontium determination bu t the high extraction of K+, Na+ and NH4+ ions results in marked influ ence.
