摘要：

The electrochemical oxidation of graphite-CrO//3 intercalation compound (GIC-CrO//3) prepared by the impregnation-dry method allowed lower chromium oxides to be removed, while they are unaffected by chemical treatment in hot 6 N HCl. The Cr(VI) formed from these oxides due to anodization in 0. 5 N H//2SO//4 is equal to only 0. 11% of the total chromium. The removal of the lower oxides restores the electrochemical properties of the host graphite, which suggests these oxides are bonded to the graphite structure.
