Abstract

Numerical modelling and simulation of Koutecky-Levich equation for NADH electrocatalytic oxidation at graphite electrodes modified with a polymer of phenothiazin formaldehyde (PPF) was performed. There were obtained the second order electrocatalytic rate constants (k_obs, _[NADH]=0) from rotating disk electrode experiments, at various concentrations of NADH and phosphate buffer with different pH values.
