Analysis of binary mixtures of vanadium with other elements by complexonometric method of amperometric titration

A possibility is shown of separate determination of binary mixtures composition of vanadium with aluminium, cobalt, nickel, zinc, iron, cadmium, molybdenum and a three-component mixture vanadium-iron-nickel by the complexonometric method of amperometric titration. The complex of vanadium with complexon 3 has been destroyed by ammonia at pH=10, and then vanadium has been titrated by a solution of the Mohr salt with 2-3 N H2SO4 as a background. One determination of binary mixture composition takes 10-12 min and of ternary mixture-15-20 min
