Coulometrie titration of +6 uranium with electrogenerated titanous ion at a platinum cathode in 8 F sulfuric acid can be performed accurately in the presence of ferrous ion as a catalyst. Amperometric end-point detection is employed. The titration is suitable for the precise assay of uranium compounds. Mixtures of +5 vanadium and +6 uranium can be titrated, because the reduction of +5 vanadium occurs at a more oxidizing potential than the reduction of +4 vanadium and +6 uranium. Using amperometric end-point detection, two end-points are observed corresponding to the reduction of +5 vanadium to the +4 state, and to the simultaneous reduction of +4 vanadium to the +3 state and +6 uranium to the +4 state. Errors are as small as plus or minus 0.3%, provided the uranium/ vanadium ratio is between 0.1 and 10. (auth)
