Abstract: Adsorption behaviors of Cu₂Zn₂SOD on mercury electrodes were studied by the electrostatic capillary curve and the relationship between polarographic ultimate current and height of mercury column in the absence of the medi-ators. The effects of impure and denatured SOD on cyclic voltammogram were investigated, confirming that no denaturation was caused during adsorption on mercury electrodes. Double potential-step chronocoulometry has confirmed that SOD adsorption on mercury electrode to be the absorption of monomolecular layer.

Keywords: Cu₂Zn₂SOD mercury electrode adsorption cyclic voltammetry double potential-step chronocoulometry
