Electrochemical parameters of ethamsylate at multi-walled carbon nanotube modified glassy carbon electrodes
چکیده انگلیسی

In this paper, some electrochemical parameters of ethamsylate at a multi-walled carbon nanotube modified glassy carbon electrode, such as the charge number, exchange current density, standard heterogeneous rate constant and diffusion coefficient, were measured by cyclic voltammetry, chronoamperometry and chronocoulometry. The modified electrode exhibits good promotion of the electrochemical reaction of ethamsylate and increases the standard heterogeneous rate constant of ethamsylate greatly. The differential pulse voltammetry responses of ethamsylate were linearly dependent on its concentrations in a range from 2.0 × 10− 6 to 6.0 × 10− 5 mol L− 1, with a detection limit of 4.0 × 10− 7 mol L− 1.
