Newell, D M

The method adopted makes use of an existing technique which has been successful for the analysis of uranium in the presence of many impurities. Using a high concentration of salting agent (55% aluminum nitrate nonahydrate) and an acidity of 1.5 N HNO/sub 3/, the plutonium is extracted quantitatively into TBP. A 30% tributyl phosphate in high-purity kerosene (as Beobase) is used. The organic layer is transferred to glass cells with 12 mm path length and read in the x-ray photometer. The interferences in the method are uranium and lanthanum; however, the latter shows no detectable effect except when present at greater than 3% of the plutonium concentration. (auth)
