Review of the Technology of Surface Modification of Activated Carbon

The functional groups,heteroatoms and chemical compounds on the surface of activated carbons are important factors to determine their adsorption capacity.The adsorption properties of activated carbons can be improved through the surface modification.In the paper,the physical and chemical properties of activated carbon were briefly discussed,and the new progresses in studies on surface chemical modification of activated carbon used as absorbent were reviewed,and the future development of surface modification technology of activated carbons was also suggested at the end of the paper.
