Catalytic-Kinetic Spectrophotometric Determination of Vanadium(V) based on its Catalytic effect on the Oxidation of Methylene Blue by Bromate

Vanadium is an important element in environmental and biological studies[1]. A variety of methods have been used for determination of vanadium; these include fluorometry, gaschromatography, x-ray fluorescence spectrometry, emission spectrometry and atomicabsorption spectroscopy. These methods either lack sufficient sensitivity and timeconsuming. In order to overcome these problems, catalytic spectroscopy is recommended [2- 4].
