Graphical abstractA sensitive electrochemical sensor with sulfonated graphene sheets/oxygen-functionalized multi-walled carbon nanotubes modified glass carbon electrode (SGSs/MWCNTs-COOH/GCE) was prepared and thoroughly characterized by ultraviolet-visible (UV-vis), Fourier-transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM). The obtained hybrid nanomaterials modified electrode was acted as a platform for the determination of clenbuterol in liver. The results indicated that SGSs and MWCNTs-COOH had synergistic effects for the determination of clenbuterol and the modified electrode showed advantages including high anti-interference ability, low detection limit and wide linearity range compared with the others working electrode, and significantly enhanced the oxidation peak currents of clenbuterol. Hence, the results demonstrated that the SGSs/MWCNTs-COOH/GCE can be applied for the detection of clenbuterol in real sample.
