Abstract In order to construct a dibutyl phthalate (DBP) molecularly imprinted electrochemical sensor, the DBP was used as the template molecule, due to the characteristics of multi-walled carbon nanotubes (MWCNTs) loaded with nano-gold to enhance the electrical conductivity of the composite material, a molecularly imprinted film was prepared on the surface of boron-doped diamond electrode (BDD) by potential deposition. The morphology of the composite material MIP/AuNPs/MWCNTs/BDD was analyzed and characterized by scanning electron microscopy (SEM), and the performance of the electrochemical sensor was characterized by cyclic voltammetry (CV), and differential pulse voltammetry (DPV) was used to detect DBP. The electrochemical sensor had a linear range of 1×10-8 ~ 1×10-5 mol/L and a detection limit of 3.3×10 -9 mol/L. The sensor was applied to the detection of DBP in water samples.

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.
