Radiometric determination of strontium with EDTA and solvent extraction

Abstract

A radiometric determination of Sr was elaborated on the basis of the principle of concentration-dependent distribution using an insufficient amount of EDTA. The uncomplexed Sr is extracted into nitrobenzene in the presence of lithium dipicrylaminate. Amounts of ∼1 μg Sr can be determined with an error of ∼4%. The method can be also used for the determination of Ca. Formulas for the calculation of theoretical calibration curves have been derived and successfully verified.
