Rapid Solvent Extraction Methods for Fission Product Separation and Analysis
Keyword(s):
SummaryA new, quick and efficient solvent extraction method of separating various constituents from irradiated fuel samples has been 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 earths. (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 sulphuric acid solutions are also described. The method usually takes half an hour and an accuracy of ± 1% is obtained.
