DETERMINATION OF PLUTONIUM IN IRRADIATED URANIUM FUEL SOLUTION BY FLOW INJECTION ANALYSIS WITH ION EXCHANGER AND SPECTROPHOTOMETRIC DETECTOR

In this paper,a new method,flow injection analysis with ion exchanger and spectrophotometric detector is reported for determination of plutonium in irradiated uranium fuel elements.A device is fixed in which a column is filled with Y-701 fine particle anion exchange resin. An automatic sample taken and a flow spectrophotometric detector are included. In this work a new efficient eluant is used. A good peak of plutonium without tail is given by the eluant. In case the ratio of Pu to U is 3×10-3 and concentration of plutonium is about 3μg/ml,the relative standard deviation is better than 5 %. It takes about 25 minutes to analyse one sample. The procedure is simple and fast.
