• A rapid and sensitive method for the determination of strontium in bone was investigated. Strontium is separated from a large amount of calcium which exists in bone and from interfering ions which depress the strontium emission using cation exchanger with EDTA as an elutriant. Strontium in the effluent, EDTA solution, can readily be determined by flame photometry without any treatment of effluent, when the enhancing effect of EDTA on the intensity of strontium flame emission is utilized effectively. Using this method, strontium content in bone could be determined from about 0. 2 g of bone ash with the error below 10% and with the standard deviation of 3. 5%. The method would be also used for the analyses of a micro amount of strontium in various calcareous materials.
