Abstract: Benzimidazole modified silver electrode which was prepared by a surface complexinduced reaction was not only stable,long-lived, but also could be used for the electrochemical reduction of NAD+.The anodic and cathodic peaks of the modified electrode were at 0.25Vand 0.10 Vrespectively.After addition of NAD+ to the test solution, the cathodic peak ofthe reductive process of NAD+ could be observed at about-0.03 Vand the peak currentwas dependent directly on the NAD+ concentration.

Key words: NAD+, Benzimidazole, Chemically modified electrode
