Chronopotentiometric And Chronoamperometric Investigations Of Uranium (Vi) In Molten Condensed Phosphates., John J. Miglio

Chemistry and Chemical Biology ETDs

The diffusion coefficient, D, of U (VI) in molten sodium metaphosphate at 694° C was determined by two independent methods. D was also determined at R values of 1.0, 1.1, 1.2, 1.3, 1.4, and 1.5, where R is the molar M₂0 to P₂O₅ ratio and M is univalent. The relative amounts of various phosphate species present in the molten state were determined by thin layer chromatography after rapidly cooling the melt and dissolving the resultant glass in water. With the above information it was hoped to determine if D is inde­pendent of the experimental method …
