Beschreibung
Zusammenfassung:	A filter medium of the present invention includes a porous carbon material having a value of a specific surface area by a nitrogen BET method of 1×102 m2/g or more, a volume of fine pores by a BJH method of 0.3 cm3/g or more, and a particle size of 75 μm or more, alternatively, a porous carbon material having a value of a specific surface area by a nitrogen BET method of 1×102 m2/g or more, a total of volumes of fine pores having a diameter of from 1×10−9 m to 5×10−7 m, obtained by a non-localized density functional theory method, of 1.0 cm3/g or more, and a particle size of 75 μm or more.
