Anodic dissolution of Mo, U3Si, and UMo in dry acetonitrile containing 0.1 M (C2H5)4 NCl and in anhydrous and 96% ethanol containing 0.1 M LiCl was studied under potentiostatic conditions. The oxidation potentials of the U and Mo alloys were determined. Anodic dissolution of UMo in the presence of β-diketones yields uranium and molybdenum chelates, and anodic dissolution of U3Si yields U(IV) chelates in an inert medium. The conditions for electrochemical preparation of uranyl β-diketonates involving oxidation of U(IV) with atmospheric oxygen in the course of electrolysis were determined. [ABSTRACT FROM AUTHOR] |
