Abstract

The complex formation between uranium(VI) ion and chloride ion in aqueous solution can be confirmed by UV-Vis absorption spectroscopy and differential pulse polarography. Absorption spectra and differential pulse polarograms of uranyl ion in hypochlorite/chloride media shows for its interaction with hypochlorite ion. Although the spectral changes for its interaction are ambiguous, new half-wave potential due to the interaction of uranium(VI)-hypochlorite ion appears in the differential pulse polarogram. Kinetic studies on the electron transfer reaction between U(IV) ion and Fe(III)(phen)3 complex in the solution containing dipicolinic acid or phosphoric acid show that the reaction rate slows down in low ligands concentration and speeds up in high ligands concentration. This result indicates that free functional group of multidentate ligands coordinated to U(IV) ion interacts at the 2 or 9 position carbon atom of phenanthroline ring in iron(III) complex. The presence of 5-sulfosalicylic acid slows down the electron transfer reaction between U(IV) ion and Fe(III) ion through the complex formation with two reactants. More information about the complex formation between U(IV) ion and 5-sulfosalicylic acid is needed for accurate explanation of the reaction mechanism. Both plutonium and uranium are extracted by TBP/dodecane from the aqueous solution, in which the post-irradiated nuclear fuel pellet  More>>

Both plutonium and uranium are extracted by TBP/dodecane from the aqueous solution, in which the post-irradiated nuclear fuel pellet is dissolved. They are back-extracted into 2M HCl solution after reducing plutonium(IV) ion to plutonium(III) ion by added U(IV) ion. Removing uranium on the DOWEX A-l anion exchange column, plutonium is eluted later for its purification. Gamma and alpha spectroscopic measurements shows the high decontamination factor and 95% recovery for the initial amounts of plutonium. (Author).}
