Abstract: A novel inlaid super-thin microcrystalline cellulose modified carbon paste film electrode was fabricated onto the surface of nichrome substrate. The super-thin electrode film was formed by direct inlaying microcrystalline cellulose modified carbon paste onto nichrome substrate.The electrochemical behavior of the electrode for ascorbic acid was examined. Results showed that the electrochemical properties of the substrate electrode was changed after inlaid the super-thin microcrystalline cellulose modified carbon paste film. Scanning electron microscope (SEM) was employed to characterize the electrode surface. The electrochemical behavior of the electrode for ascorbic acid was investigated by various electrochemical techniques.The electrode exhibited an excellent enhancement of the current response for AA. The proposed electrode can be applied to determine AA in practical samples.
