The surface modified activated carbon according to the present invention and the surface modified activated carbon produced by the method can be used for modifying the surface of activated carbon only by a simple process that saves cost and time and to treat wastewater containing organic pollutants It is possible to remove the anionic contaminant which is difficult to remove in the process of removing the contaminant, and other contaminants can improve the removal efficiency. In addition, the surface modification of the activated carbon improves the ability of the activated carbon to adsorb pollutants, thereby providing activated carbon having high pollutant removal efficiency.
