Abstract  

A coulometric titration method with controlled current and amperometric end-point detection with two indicator electrodes was worked out to determine neptunium in solutions which were obtained while treating the spent nuclear fuel. This method allows to determine in presence of 1000-fold quantities and more of Pu, Ce, Cr, Fe, Mn, 1000-fold quantities and more of U. The error of determination is 0.2% for pure Np solutions and increases up to some precent in presence of large amounts of impurity.
