Abstract An analytical procedure for the determination of strontium in environmental media by flame photometry at 461 m mu is described. Strontium and other alkaline earths are separated from interfering ions such as phosphate by oxalate and nitrate precipitations. Calcium is removed by ion exchange chromatography after preferential chelation with Versene at pH 5.0. Monovalent ions are washed from the ion exchange resin with 0.5N HCl prior to eluting strontium and barium with 3N HCl. Strontium-85 tracer is used to monitor strontium losses during purification. As little as 0.05 mg of strontium may be measured with 5% error. Strontium was determined in food, water, excreta, and bone by this method. (auth)
