An activated carbon was prepared from waste wood shavings by simple carbonization in a muffle furnace. Wet oxidations of the carbon were carried out with nitric acid, hydrogen peroxide and potassium persulphate. The physicochemical, chemical, FT-IR, N2 adsorption, SEM, TG, DTG and XRD characterizations were done. Though the carbon produced from simple pyrolysis possessed some acidic and basic groups with porous texture, modifications with the chosen reagents improved the surface heterogeneity and porous characteristics. These surface chemical and textural characteristics were presented in this paper.
