Kinetic determination of rutin

Abstract

A kinetic method is described for the determination of rutin based on its inhibitory effect on the Fe(II)-AA catalysis of the oxidation of C6H5COONa with hydrogen peroxide. Detection limit of this method is 0.16 ng cm-3. The relative error ranges between 0.9 to 9.8%for the concentration interval 0.82 ng cm-3 to 8.2 ng cm-3. Kinetic equations are proposed for the investigated process. The effects of certain foreign ions upon the reaction rate were determined for the assessment of the selectivity of the method.
