Coal-based activated carbon has a unique pore structure and excellent adsorption performance and is an important adsorption material. The pore structure and surface chemical properties of activated carbon have an important impact on its adsorption performance. Currently, activated carbon is widely used in wastewater treatment. According to the requirements of wastewater treatment, research on surface modification of activated carbon has gradually increased. There are many methods for chemical modification of activated carbon surface, among which acid and alkali modification methods are simple and convenient. The acid- and alkali-soluble substances in activated carbon can be dissolved with acid and alkali, but the skeleton structure is not destroyed. The specific surface area of modified activated carbon increases and the adsorption capacity of organic matter increases.
