ABSTRACT:
A carbon-based adsorbent comprising active carbon provided with electron-donative surface functional groups which are bonded directly and chemically to graphite constructing the surface of the active carbon and are coordinated with metallic ions to form chelate structures, which has adsorbing power similar to that of common active carbon and additionally the ability to remove specific harmful gas molecules and smelling gas molecules from air, thus being especially effective for gas filters.
