OPEN ACCESS
A selective and sensitive molecularly imprinted electrochemical sensor was prepared based on the electropolymerization of methylthionine chloride on the multi-walled carbon nanotubes modified glassy carbon electrode. The proposed sensor was applied to the determination of sulfamethoxazole which showed a linear range of 2.4 to 23.6 µM, and a detection limit of 0.81 µM.The determination of sulfamethoxazole in real samples was also studied.
