Abstract:
The electrochemical activities of graphite electrodes, which were treated by H2S04 98% at 60"C, have been investigated using anodic polarization method. The results showed that: in the H2S04 IM, the overpotential of Oxygen and Hydrogen of industrial graphite electrodes, after being treated are lower than non-treated and spectra -coal electrodes. They has ability to adsorb Ni2+ ion. The electrochemical conversion ability of Ni2+ to Ni3+ of the spongy graphite containing Ni2+ electrode much higher than pure Nickel electrode in the KOH solution.
