Cesium is precipitated as dipicrylaminate which, after washing with ether, is dissolved in ethyl acetate. The Cs is then extracted from this solution by an aqueous acid solution. The ethyl acetate phase containing the dipicrylamine from decomposition of Cs dipicrylaminate is colorimetrically analyzed. The principal interest in this method lies in the possibility of radiochemical determination of carrier-free Cs by decontaminating the solution put in the spectrophotometer. (T.R.H.)
