摘要：

The oxidation of uranium (III) in acid solutions has been studied by spectrophotometric measurement in an inert gas atmosphere. Uranium (III) obtained by reduction of uranyl salt with zinc amalgam was oxidized more rapidly than that prepared by dissolution of uranium amalgam or electrolytic reduction of uranyl ion. The oxidation is strongly catalysed by copper or lead ion contained as a trace impurity in zinc. The autoxidation and the metal surface catalysed oxidation of uranium (III) are discussed. © 1979.
