Adsorption properties and concentrations of surface oxygen groups were determined for commercial carbons (WG-12 and WG-15) and commercial carbons modified by water, hydrochloric acid and nitric acid (V). Basic parameters of the porous structure of the present carbons were determined according to low-temperature isotherms of nitrogen adsorption. Moreover, concentrations of surface oxygen groups were determined by the Boehm and TGA methods. Modifying agents used here substantially affect the porous structure and chemical properties of the surface of activated carbons. The use of nitric acid (V) affects chemical properties most.
