Fudge, A J; Wood, A J; Banham, M F

A method is described for the determination of plutonium in the range of from 1 to 10 mg. The plutoniunn, in sulfate solution, is reduced to the trivalent state by the addition of excess chromous sulfate in 1M sulfuric acid. The excess chromous sulfate is air oxidized until a steady potential is observed from the platinum/calomel electrodes. The plutonium(III) is then oxidized to plutonium(IV) with a standard solution of ceric sulfate delievered from an Agla micrometer syringe burette. A procedure is described for the separation of plutonium from elements that would cause interference with the titration. A precision of combination rat 0.2% ( 2/ spheres con ) of plutonium is attained in the range of from 2 to 10 mg with a similar accuracy. (auth)
