摘要

The kinetic parameters for the electrocatalytic oxidation of di hydronicotiamide adenine dinucleotide (NADH) at glassy car-bon electrodes modified with an electropolymerized film of nile blue A (PNB) have been determined based on rotating disk electrnode measurements. The rate constant for the chemical reaction between NADH and PNB is strongly influenced by NADH concentration and the pH value of solution, and it decreases with increasing NADH conectration, indicating that the electrocatalytic process proceeds via the formation of an intermediate of charge-transfer complex between NADH and PNB.
