Cl-2 was adsorbed from waste gases (140 mg/m(3)) on 4 com. activated C at 20 degrees C for 16.3-49.4 h. Their phys.-chem. and structural properties were detd. The most efficient Cl-2 removal from dry flue gases was achieved on the activated C produced from coconut shells and from wet flue gases was achieved on activated C used in chromatog.
