THE SPECTROPHOTOMETRIC DETERMINATION OF VANADIUM AS MOLYBDOVANADIC ACID
Journal Article
·
· Analytica Chimica Acta (Netherlands)
A colored complex formed by the condensation of the oxy-acids of molybdenum (VI) and vanadium(V) in a 5 to 1 ratio is used as the basis for a spectrophotometric method for vanadium. The absorbance or the intense yellow complex is measured at 360 m mu . The color is stable for at least 24 hr and follows Beer's law at a concentration of 2- 10/sup -5/ to 6- 10/sup -4/M vanadium. A standard deviation of 0.056% in steel samples containing 2.04% vanadium was obtained for five determinations. Factors affecting the color formation and the analytical applications to the determination of vanadium are presented. (auth)
