Spectrophotometric determination of micro amounts of molybdenum and vanadium by reduction of iron(III) in the presence of ferrozine.
Molybdenum and vanadium, in the range 0.1-1 ppm have been determined with a relative precision of 1-2% with iron(III) in the presence of Ferrozine. The separation of molybdenum and vanadium from interfering elements has been achieved by ion-exchange with either cation-exchange RG 50 followed by anion exchanger AG 1-X8, or the exchange-resin NBL 17.
