Abstract
A rapid and reliable method was developed for the separation of radiocesium from fission-product mixtures. Stannic chloride is used to precipitate cesium selectively as cesium chlorostannate, Cs2SnCl6, from a 50 (v/v)% solution of concentrated HCl in ethyl alcohol. Usually, the major portion of contaminants is removed by one scavenging step followed by two precipitations of cesium. The method is comparable with the perchloric acid and tetraphenylboron precipitation methods for cesium with respect to decontamination factors, carrier yields, analytical time, and accuracy. It was applied satisfactorily to a variety of samples.
