| Abstract: |
| Pyrite powder was prepared by mechanical activation.By adopting pyrite powder microelectrode as working electrode,the electrochemical behavior of pyrite powder under mechanical activation in absolute ethyl alcohol was studied through cyclic voltammetry.Proper amount of cationic surfactant,such as cetylpyridinium chloride,is added as ion conductor in the experiment.Based on the Nernst equation,reversibility of pyrite powder microelectrode was discussed.The relations of peak current,peak potential and semi pe... |
