摘要：The studies show the regeneration process of KMnO₄ on stainless stell electrode, comparative with the ones obtained on platinum electrode. The studies were made through cyclic voltammetry at concentrations of support electrolyte (KOH) of about 5 to 10%, at 25-40^ºC temperature, KMnO₄ concentration until 6•10^-2 M and maximum concentration of quinoxaline until 2.61•10^-2 M, in electrolyte solution. It seems that on stainless steel electrode is not possible to do the oxidation of Mn⁶⁺ to Mn⁷⁺ like on paltinum [1,2], nickel [3] or copper electrode [4]. However, a final decision will be made after the effectuation of new investigations (preliminary synthesis).
