Adsorption properties of halogenated organic compounds using heat-treated sugi bark
Summary Sugi (Japanese cedar, Cryptomeria japonica D. Don) barks were heated at 300 - 900oC to investigate their adsorption capacities for trichloroethylene (TCE) from aqueous solutions. The maximum adsorption capacity for TCE was obtained with the barks pyrolyzed at 900oC and the value was 5 times larger than that of a commercial activated carbon.
