Diantipyryl-(p-hydroxy)-vinylphenylmethane (DApHVM) was synthesized and its color reaction with chromium(Ⅵ) was studied. In the presence of Mn(Ⅱ), DApHVM reacts with chromium(Ⅵ) to form a red product in phosporic acid medium. The molar absorptivity of the Cr(Ⅵ)-DApHVM complex is l .76 x 106L.mol-1. cm-1 at 540 nm. Beer's law is obeyed in the of 0 ~ 30 μg/L. This method has been applied to the determination of chromium(Ⅵ) in water with satisfactory results.
