▎ 摘  要

Modified graphene oxide (GO) electrochemical sensor was successfully used to determine ascorbic acid (AA). Manganese (Mn)-doped ZnO nanorods (ZnO NRs) was synthesized through the electrochemical technique and applied for modification of GO/glassy carbon electrode (GCE). Field emission scanning electron microscopy and X-ray diffraction analysis were applied to characterize the morphological and structural properties of synthesized Mn-doped ZnO NRs. Cyclic voltammetry and differential pulse voltammetry analysis were used to electrochemically sensing the properties of Mn-doped ZnO NRs/GO/GCE. The electrochemical studies exhibited the modified electrode had fast response, selective and stable in determining AA. The sensitivity and detection limit of sensor were estimated 0.169 mu AmM-1 cm(2) , 0.02 mu M, respectively. The sensor response was studied to determine AA content in orange juice as real sample.
