详细
Oxidation of Np(V) to Np(VI) with xenon trioxide in a 0.5–1.4 M HClO4 solution was studied by spectrophotometry. The reaction rate is described by the equation–d[Np(V)]/dt = k[Np(V)][XeO3], where k = 4.6 × 10–3 L mol–1 s–1 in 1 M HClO4 at 92°С. The activation energy is close to 92 kJ mol–1. The activated complex is formed in contact of NpO2+ and ХеО3 without participation of Н+ ions. The activated complex transforms into NpO22+ and the products: ОН, Хе, and О2. The ОН radical oxidizes Np(V). Admixtures of Со2+ and especially Fe3+ accelerate the Np(V) oxidation.
