A new, quick, and efficient solvent extraction method of separating various constituents from irradiated fuel samples was evolved. In this method, the following groups are isolated, using diethyl hexyl phosphoric acid, (HDEHP) as solvent: (1) Ru, Cs, Sr, Ba; (2) Ce; (3) Y plus rare eanths; and (4) Zr and Nb. Further solvent extraction methods are used for separation of individual elements. A rapid method is described for the extraction and estimation of zirconium-95 from fission product solution utilizing HDEHP. The fission products are normally in nitric or hydrochloric acid solution but extractions from sulfuric acid solutions are also described. The method usually takes haif an hour and an accuracy of plus or minus 1% is obtained. (auth)
