Cyclic voltammetry (cv) is popular for it’s relative simplicity and it right information content . It is used most often as a diagnostic tool for elucidating electrode mechanism .In this experiment , one will practice polishing solid electrode , run the cyclic by using cyclic votammetry (staircase) in normal mode by setty pretreatment , measurement and potentials for counter electrode such as Platinum rod , Gold disk and glassy carbon electrode , respectively and then cyclic votammogram of each counter electrode were showed by peak of Platinum , Gold and Glassy Carbon are difference when cyclic voltammogram are differences.
