Abstract: The paper examined the influence of hydrogen peroxide and ozone and singlet oxygen co-agents on the functional groups of the carbon black surface. The influence of the ambient temperature and the concentration of the reactants on protogenic functional groups (carboxylic and phenolic) generating has been studied. To assess the functional composition methods of titration with alkali of different strengh, differential potentiometer, pyrolysis gas chromatography have been used. It was found that the carbon oxidation depends on the sample structure. It is shown that carbon oxidation with hydrogen peroxide depends on the co-agent nature. With singlet oxygen used as a co-agent, carboxyl groups with the lowest pKa of about 2are generated on the carbon surface. When using ozone pKa of the group is higher than 2.
