Abstract:An electrochemical study of several solids, such as MnCl2 · 4 H2O(s), MnF3(s), Fe2O3(s), Fe3O4(s) and MnO2(s), using carbon paste electrodes with electrolytic binders, is described. Results obtained have been compared with results of earlier electrochemical experiments to carry out the characterization of technological material, such as manganese ferrite. The voltammograms obtained represent the “electrochemical spectra” of solid or dissolved substances that can be used to characterize the material without previous solubilization, as charge transfer processes can proceed in the solid or dissolved state, depending on the solubility in the binder used. Received: 9 December 1996 / Accepted: 14 April 1997
Keywords:Voltammetry  Carbon paste electrode with electrolytic binder  Manganese compounds  Iron compounds
