摘要：

The authors studied the reduction of vanadium(V) in phosphoric-acid-citrate-edetate solutions in order to develop its polarographic determination in iron-contaning materials. Polarography with triangular potential sweep was used for the investigations. It has been established that the polarographic characteristics of vanadium(V) depend on solution pH. At pH less than 3 the reduction and oxidation wave are not seen. At pH between 3 and 10 the values of the maximum currents remain constant, while the potential of the second cathodic peak shifts somewhat in the negative direction with increasing pH. At pH greater than 10 the polarograms seriously deteriorate.
