摘要
The features of chemical oxidation of graphite in H2SO4 are discussed. Measurements of currentless potentials of K2Cr2O7, KMnO4, (NH4)2S2O8 and complex salt Ce(SO4)2.4(NH4)2SO4.2H2O solutions in 96% H2SO4 were carried out. Correlation of the redox potentials of oxidizers to the stage number of graphite hydrogenosulfate (GHS) is established. It is proposed to use the standard redox potential scale to choose the oxidizers for the formation of a given stage GHS. On the basis of this approach, numerous oxidizers for GHS formation are considered. For the first time, ozone and Ce(IY) sulfate were applied for GHS production. The stage 1 GHS is obtained in accordance with standard potentials of these oxidizers.
