Abstract: The electrochemical behavior of imidacloprid(IDP)on glassy carbon electrode has been investigated by cyclic voltammetry. The result shows that the electrochemical reduction of IDP is irreversible and controlled by diffusion. At 25 ℃, the numbers of the electrons transferred of IDP in the electrochemical reaction are four. The diffusion coefficient of IDP is 2.44×10?6 cm2?s?1 and the diffusion activation energy is calculated to be 9.33 kJ?mol-1.

Key words: imidacloprid, electrochemistry, cyclic voltammetry, linear sweep voltammetry
