| description | An electrochemically reduced graphene oxide was produced by cyclic voltammetric technique and ERGO modified electrode used a new sensor for determination of caffeic acid (CA). The reduced graphene oxide were characterized by Fourier transform infrared spectroscopy (FTIR), Scanning electron microscope (SEM), Raman spectra and cyclic voltammetry (CV). The results reveals electrochemically reduced graphene oxygen content could be decreased significantly. The electrochemical sensor properties examined by cyclic voltammetry and differential pulse voltammetry (DPV). Our proposed sensor ERGO/SPCE exhibited tremendous electrochemically activity towards oxidation of the CA and enhanced current response compared with bare SPCE and GO/SPCE. The wide linear range from 0.2 to 2100 μM and limit of detection 0.064 μM were obtained. The proposed sensor ERGO/SPCE was successfully applied to detection of caffeic acid in wine samples. |
