| Abstract: |
| Activated carbon is one of the most widely used absorbents in the field of removing various organic substances in polluted environments, due to its abundant pore structure and a high degree of surface reactivity. However, the surface chemical properties of activated carbon are rich in hydrophilic functional groups. This means that when water molecules and organic pollutants coexist, they compete for active sites on the surface of activated carbon. In this situation, activated carbon tends to preferentially adsorb water molecules, which drastically diminishes its adsorption capacity of the desired organic pollutants. This negatively affects its efficiency when used in humid environments. Therefore, how to improve the moisture and water resistance of activated carbon is an urgent problem that needs to be resolved in the application of an complex multi-component environment. A large number of studies have shown that modifying activated carbon to be hydrophobic or superhydrophobic can effectively tackle the thorny problem. |
