| Abstract: | The irreversible adsorption of chelating ligand of 6, 7-dimethyl-2,3-di(2--pyridyl)quinoxaline(DMDPQ) on pyrogenic graphite electrodes were examined by surface cyclic voltammetry, from which the two electron, two proton electrochemical reation of pyrazine group in the studied moleculos were identified.The formal potential and diffusion coefficient of DMDPQ ligand were also determined. |
