Radiolytic oxidation of americium(III) to americium(V) and plutonium(IV) to plutonium(VI) in saline solution
- 1. Technische Univ. Muenchen, Garching (Germany, F.R.). Inst. fuer Radiochemie
Description
The redox behaviour of americium and plutonium in concentrated NaCl solutions (more than 1 M NaCl) under the influence of their own alpha radiation is investigated. The α radiation (greater than 0.5 Ci l-1) induces the oxidation of the Cl- ion and hence creates a strongly oxidizing medium in which americium(III) and plutonium(IV) present initially become oxidized to americium(V) and plutonium (VI) respectively. The oxidation kinetics depend on the α-radiation dose, NaCl concentration and pH of the solution. Americium(V) remains stable at pH>8 and plutonium(VI) in a wide range of pH. (orig.)
