Abstract
Magnetized active carbon composition consisting of active carbon and a magnetized ferromagnetic material mixed therewith has enhanced properties of active carbon, and may be used in order to remove carbon monoxide, hydrogen and nicotine from tobacco smoke and to control reactions in soil. The above properties are enhanced by applying a magnetic field and/or an electrostatic field to the magnetized active carbon.
