Abstract

The authors examine some of the regularities displayed when UO2 is oxidized by manganese dioxide in sulfuric acid solution, both without and with added iron ions. It is shown that the redoX potential indicates only the potential capacity of the system, and is not an unambiguous criterion of the degree of oxidation of UO2; the effective reaction rate is limited by the reaction mechanism.

A study is made of the way in which the degree of oxidation and dissolution of UO2, at 20 and 85°C in sulfuric acid solution, depends On the redox potential when MnO2 and Fe (II) are added. The relation is expressed by an S-shaped curve. It is shown that, during oxidation of UO2. by manganese dioxide in sulfuric acid solution, iron ions act as a catalyst.
