Kinetic determination of rutin [PDF]
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

Kinetic determination of morin nanoamounts [PDF]
A kinetic-spectrophotometric method is proposed for the determination of morin. The method is based on the inhibition effect of morin on the oxidation of C6H5COONa by hydrogen peroxide in the presence of the complex Fe(II)-AA(ascorbic acid), which acts ...
