Disproportionation of Pu(V) in K10P2W 17O61 solutions

In solutions of unsaturated heteropolytungstate K10P 2W17O61, Pu(V) disproportionates in a wide pH range; it is a first-order reaction with respect to Pu(V), and its rate only slightly changes in the pH range from 0.7 to 4.0. The activation energy E a of Pu(V) disproportionation was determined as 78.6±2.0 and 64.2±3 kJ mol-1 at pH 2.0±0.1 and 4.0±0.2, respectively. The thermodynamic parameters of activation ΔH≠ and ΔS≠ were evaluated. Published data on disproportionation of Np(V) and Am(V) in K10P2W 17O61 solutions were analyzed.
