Аннотация
The reduction of penta- and hexavalent Np ions to the tetravalent state with Fe(II) sulfamate in HNO3 solutions was studied. The dependence of the degree of the Np reduction on the temperature, time, concentrations of HNO3 and Fe(II) sulfamate, and Np(V) to Np(VI) concentration ratio was studied. The influence of the solution flow rate through the chromatographic column on the degree of the Np recovery was examined. A procedure was developed for Np isolation and determination of its gravimetric content in spent nuclear fuel.
