摘要：

The Np(V) reduction with hydroxyethylhydrazine is described by the equation -d[Np(V)]/dt = k1[Np(V)][HOC2H4N 2H4+] + k2[Np(V)][Np(IV][H +]1.8, reflecting its main and autocatalytic pathways. The rate constants are k1 = 0.31±0.04 l mol-1 min -1 and k2 = 4.04±0.11 l2.8 mol -2.8 min-1 at 80°C and ionic strength μ = 4. The activation energies are E1 = 90±6 and E2 = 116±4 kJ mol-1, respectively. The autocatalytic pathway is limited by the reaction between hydroxyethyldiazenium ions, HOC 2H4N2H2+ and protonated Np(V) ions. ©2005 Pleiades Publishing, Inc.
