Abstract: | The analytical reactions of bismuth iodide and stannic chloride with cesium and rubidium are used for the radiochemical separation
of these two elements. The method consists in precipitating potassium, rubidium and cesium as their cobaltinitrites, selective
isolation of cesium as cesium bismuth iodide from glacial acetic acid, and subsequent separation of rubidium from potassium
as chlorostannate from conc. HCl. The results obtained by the present method for the rubidium and cesium contents of the different
U.S.G.S. standard rock samples are compared with those reported using methods of comparable accuracy. The suitability of the
method for the analysis of fall-out samples for their radiocesium (137Cs) contents has been demonstrated. |
