Calcium and Sr were separated on an Amberlite IR-120 resin column with ethylenediaminetetraacetic acid, and Ca was determined spectrophotometrically and in the presence of ethylenediaminetetraacetic acid. Calcium recovery from the CaEDTA complex was 85% at the 100 mu g level. Recoveries of Ca from the CaEDTA complex in the presence of large quantities of EDTA were improved with the addition of Cu chloride. Calcium and Sr were separated on the Amberlite IR-120 column; ammonium EDTA was used to elute the Ca. Recovery of Ca contaminated with 40% Sr was 100%. The remainder of the Sr, approximately 47%, was recovered free of Ca. A total of -86% of the Sr added was found. (auth)
