Abstract

The new reagent FHA gives a purple-colored complex with Vanadium(V) in an acidic medium. The complex exhibits a wavelength of maximum absorption at 475 nm. The colored system obeys Beer's law in the concentration range of 0.2-16 μg ml–1. The molar absorptivity and Sandell's sensitivity were found to be 2.6 × 104 litre mol–1cm–1 and 0.0136 μgcm–2. The color reaction has been investigated to develop a spectrophotometric method for the determination of Vanadium (V) in an aqueous medium. The reagent has been used for the determination of vanadium in environmental and biological samples.
