Investigation into the dissolution and direct assay of high-fired plutonium dioxide. [Fusion-melt with potassium pyrosulfate and sodium peroxide]

Investigation into the dissolution and direct assay of high-fired plutonium dioxide. [Fusion-melt with potassium pyrosulfate and sodium peroxide] [electronic resource]

A fusion-melt and dissolution assay method has been developed and tested for the quantitative analysis of high-fired plutonium dioxide. The method employs fusion of the plutonium dioxide at temperatures greater than the melting point of an eutectic mixture of potassium pyrosulfate plus sodium peroxi...

Description
Summary:A fusion-melt and dissolution assay method has been developed and tested for the quantitative analysis of high-fired plutonium dioxide. The method employs fusion of the plutonium dioxide at temperatures greater than the melting point of an eutectic mixture of potassium pyrosulfate plus sodium peroxide. The resultant melt is then titrated directly by either controlled potential coulometry or a gravimetric titration, using standardized ceric sulfate as the titrant. It has been concluded from these investigations that by using the techniques described, high-fired plutonium dioxide (stochiometric) can be quantitatively dissolved and assayed to a degree heretofore beyond the state-of-the-art, while showing direct traceability to the Federal standards. After fusion, the dissolution and direct assay is applicable to existing routine analytical procedures. The method was designed so as to minimize physical handling, simplify the chemical operations, and maximize the personal safety of the analyst at an appreciable cost savings per analysis. (auth)
