The kinetics of the reaction between Np(V) and hydroxylammonium chloride in perchloric acid solution was studied at 70°C. In perchloric acid solutions from 1.0 <BR>to 1.5 mol•dm<SUP>-3</SUP>, the reaction rate is described by <BR>-d[Np(V)]/dl = k[Np(V)][NH<SUB>3</SUB>OHCl]<SUP>1.6</SUP>[H+]<SUP>2.1</SUP>, <BR>where the rate constant k= (6.7 ± 0.3) × 10<SUP>-2</SUP> mol<SUP>-3.7</SUP> dm<SUP>11.1</SUP> min<SUP>-1</SUP>. Detailed studies of the dependence of the rate on the concentrations of hydroxylammonium ion and chloride ion showed that the reaction is much accelerated by chloride ion.
