Abstract: The theoretical curves which describe the 1.5th order derivative, e', and 2.5th order derivative of current, e", vs. the electrode potential, E,are presented In anodic stripping processes at thin mercury film formed in situ on the rotating glassy carbon disk electrode. The theoretical curve equations are.whereandwhereThe numerical calculations have been programmed in BASIClanguage for computation with APPLE II PLUSmicrocomputer in accordance with above equat-ions.
