It is difficult to prepare high-quality products with specific functions by traditional methods Activated carbon It is necessary to change the physical and chemical properties of activated carbon surface and optimize the full potential of its adsorption performance to meet the growing demand of production, life and engineering experiments. Although the specific surface area and the spatial layout of pore structure play a decisive role in the adsorption capacity of activated carbon. However, surface chemical properties, such as the type and amount of surface compounds, surface oxygen-containing functional groups and surface heteroatoms, greatly affect the interaction between polar or non-polar adsorbents and activated carbon. The existence of these oxygen-containing functional groups directly or indirectly affects the micro physical and chemical properties of the surface of activated carbon, and affects the macro adsorption performance of activated carbon. In order to improve the adsorption of water vapor, this study used oxalic acid ethyl acetate acid hydrolysis to Honeycomb activated carbon Modification and introduction of hydrophilic functional groups.

Activated carbon removes organic solvent vapor from the air. In the activated carbon of plant waste, the adsorption capacity of activated carbon is relatively high, mainly due to its large micropore volume. Comparison of model parameters characterizing the interaction energy with butanol. Corresponding to adsorption isotherm, it indicates that this is conducive to the removal of low concentration butanol vapor.
