In this paper, the electrochemical behaviors of rutin at the MWNTs-IL-Gel/glassy carbon electrode (GCE) were investigated. Good electrocatalysis behavior towards the oxidation of rutin with enhancement of the redox peak current and decrease of the peak-to-peak separation was demonstrated. The electrochemical parameters of rutin were calculated giving values of the charge-transfer coefficient (alpha) and the electrode reaction standard rate constant (k(s)) as 0.47 and 0.2s(-1), respectively. In addition, the MWNTs-IL-Gel/GCE was characterized by different methods including electrochemical impedance spectroscopy (EIS), scanning electron microscope (SEM), clay film thickness, and UV-vis spectra. The oxidation peak currents of rutin in such modified electrode increased linearly with the concentration of rutin in the range from 7.2 x 10(-8) to 6.0 x 10(-6) mol L(-1) with a detection limit of 2.0 x 10(-8) mol L(-1). These results suggest that the proposed electrode can be used for sensitive, simple and rapid determination of rutin. |
