An electrochemically reduced graphene oxide (ERGO) modified glassy carbon electrode (GCE) was used as a new voltammetric sensor for the determination of ferulic acid (FA).The morphology and microstructure of the modified electrode was characterized by scanning electron microscopy (SEM) and Raman spectroscopy analysis.The sensing properties of modified electrode to FA were investigated by means of cyclic voltammetry (CV) and differential pulse voltammetry (DPV).It was found that ERGO was electrodeposited on the surface of GCE by using potentiostatic method.The proposed electrode exhibited electrocatalytic activity to the redox of FA because of excellent electrochemical properties of ERGO.The transfer electron number (n), electrode reaction rate constant (ks) and electron-transfer coefficient (α) were calculated as 1.12, 1.24 s 1, and 0.40, respectively.Under the optimized conditions, the oxidation peak current was proportional to FA concentration at 8.488 × 10-8mol L-1 to 3.892 × 10-5 mol L-1 with detection limit of 2.06 × 10-8 mol L-1.This fabricated sensor also displayed acceptable reproducibility, long-term stability,and high selectivity with negligible interferences fiom common interfering species.The voltammetric sensor was successfully applied to detect FA in A.sinensis and biological samples with recovery values in the range of 95.72-104.51%.
