abstract = "This paper presents a comparative study on the electrochemical behavior of the flavonoid rutin on a rigid carbon-polyurethane composite electrode and on a glassy carbon electrode. The electrochemical oxidation reaction of rutin was found to be quasireversible and affected by adsorption on the electrode surface. A square-wave voltammetric method was developed for determination of rutin in green tea infusion samples using the RCPE electrode and data treatment by a deconvolution procedure. The detection limit achieved in buffered solutions was 7.1 × 10-9 mol L-1 using the RCPE and 1.7 × 10-8 mol L-1 using the GC electrode the average reproducibility for five determinations being 3.5%.",
