Study on Color Reaction of Rutin with Fe(III) and Its Application

Dai Yun

Abstract

The color reaction of rutin with Fe(Ⅲ)and its IR, UV character were studied. In the presence of pH=5.6 buffer solution and CTMAB medium . rutin can reacts with Fe(Ⅲ)to form a stable 3:1 complex. The malor absorptivity is 1.38?104 L.mol -1 .cm -1 at 590nm. Beer's law is obeyed in range of 0-50μg/25ml. This method can be applied to the determination of Fe(Ⅲ) in tobacco environmental sample with satisfactory results.
