Abstract: | The oxidation of a carbon-carbon composite sorbent by a number of oxidants results in the variations of the chemical nature
of the surface, including an increase in the overall content of surface oxygen-containing groups and, in separate cases, increased
variations in its structure-chemical characteristics, primarily in an increase in the percentage of large mesopores. The oxidative
modification of the initial sorbent increases the hydrophilicity of its surface and enhances the specific sorption of water
vapors. |
