Description
Separation and concentration of the different neptunium oxidation states can be achieved with continuous electrophoretic ion focusing. Differences between complex stability constants of the particular neptunium complexes are used to separate the neptunium oxidation states in an electric field. After preparation of Np(IV) and Np(V) in solution, separation in dependence of pH, complexing agent and conductivity of the samples is investigated. (orig.)
