title: Determination of strontium in environmental media.
abstract: A procedure is described for the determination of strontium in natural materials by name photometry. An alkaline fusion of the ashed sample followed by dissolution in dilute acid gives a preliminary separation. Further separation of strontium is obtained by sorption on Dowex-50 resin from an EDTA solution at pH 5.1 followed by elution of the alkali metals with 0.5M hydrochloric acid, and of the strontium with 3M hydrochloric acid. The emission line at 460.7 mmu; is used and the intensity enhanced by the addition of s-butanol to the solution.
