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

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