Electrochemical behavior of benzo[c]cinnoline-N-oxide was studied. Two discrete 2 and 4 electron reduction waves in acidic media but only one wave in basic media were observed in ethanol-BR buffer system (1:5 v/v). The number of electrons transferred and the difussion coefficient were determined by using various voltammetric techniques, such as sampled current polarography, cyclic voltammetry, chronoamperometry, chronocoulometry and constant potential coulometry. Adsorption of the molecule on the surface of the mercury drop was analyzed and this phenomenon was exploited to calculate the diffusion coeffcient of benzo[c]cinnoline-N-oxide. A mechanism for the electrode reaction is proposed.
