PRECISE DETERMINATION OF PLUTONIUM BY POTENTIOMETRIC TITRATION
Micro amounts of plutonium are quantitatively oxidized with fuming perchloric acid, and plutonium(VI) is reduced to plutonium(IV) with a slight excess of standand iron(IV) solution which is then titrated automatically with cerium(IV). Large sample sizes and weight burets are used for precise results. An average value for the plutonium content of a high purity metal sample of 99.98%, with a standard deviation of 0.02%, was obtained for 11 determinations, using 3- to 5-gram aliquots of a solution containing 63.111 mg. of the metal per gram. From the total of the concentrations of the trace impurities, the plutonium content of the sample was calculated to be 99.98%. a 26 foreign metals investigated, chromium, gold manganese, vanadium, and platinum seriously interfered, The spectrophotometric titration of plutonium is also discussed.
