Simultaneous Spectrophotometric Determination of Chromium(VI) and Vanadium(V) by using 3,4-Dihydroxybenzaldehyde isonicotinoyl hydrazone (3,4-DHBINH)

A simple, rapid, highly sensitive and new simultaneous spectro- photometric method is proposed for the analysis of chromium(VI) and vanadium(V) without separation by using 3,4-dihydroxybeznaldehyde isonicotinoyl hydrazone (3,4-DHBINH). The reagent reacts with the two metal ions in acetic acid-sodium acetate buffer of pH 5.5 and gives maximum absorbances at 400 nm and 360 nm for...
