Amperometric determination of vanadium as vanadyl selenite

Abstract

An amperometric titration procedure for the determination of vanadium as selenite in 0.044 M ammonium acetate and 50-55 per cent alcohol at a pH between 5.3-5.5 has been described. The titration is carried out at -1.10 V versus S.C.E. A V-shaped curve is obtained. The molar ratio of Se:V (1:1) supports the formation of a normal selenite VOSeO3. © 1962 Springer-Verlag.
