The radiochemical separation of strontium by an amalgam-exchange technique was critically evaluated with a saturated aqueous solution of potassium chloride as an exchange medium. With an optimized procedure strontium yields of about 34% were obtained, although mineral acids and alkalies above 0.1M decrease the yield considerably because of decomposition of the amalgam. In studies with tracers of 16 different elements, the technique gave considerably better decontamination than the fuming nitric acid procedure. The simple separation can be carried out in 8 min with no special equipment required, while application of the method to fall-out rain-water samples requires abou 40 min. The procedure can also be easily adapted to the preparation of a Y/sup 90/-free source of Sr/ sup 90/. (auth)
