✦ Synopsis

CycIic vohammetry was applied to investigate the Cr" KY' and Fe" /Fe:+ redox couple reactions in HCI electrolytes on highly oriented pyrographite electrodes activated by oxidative pretreatment. The activation effect observed after the oxidative pretreatment was very unstable for the Cr"/C?+ reaction in comparison to the Fe)+ reduction. It is thus concluded that acidic surface oxides are participating in the redox reaction. These oxides are reduced, however, in the case of Cr" reduction near the potential of hydrogen evolution.
