Description
Summary:Au/XC-72 nanoparticles prepared via microwave-assisted polyol processes were used as the active materials for methimazole detection. The Au/XC-72 modified electrode shows an excellent catalytic activity toward oxidation of methimazole, the cyclic voltammetry of methimazole displays two pairs of well-defined, quasi-reversible redox peaks. The oxidation of methimazole on Au/XC-72 modified electrode is a diffusion-controlled and a one-electron transfer process. The fixed-potential amperometry technique was used for the determination of methimazole and a linear dependence of anodic current on methimazole concentration was obtained in the range of 19.9–100.91 μM.
