Abstract:Several methodologies are reported in the literature that aim to remove adsorbed substances from polycrystalline platinum electrode surfaces in order to obtain the real electroactive areas. However, those procedures often use highly toxic reagents for humans. Because of that, a methodology for the pretreatment of both the platinum electrode and the working glassware using less harmful solutions to humans and the environment was developed. All materials should be immersed in KMnO 4 1 % for 12 h for the removal … Show more
