摘　　要：本研究主要目的是要提高活性炭对M IB的处理能力。活性炭分别用N2和H2进行热处理。活性炭快速小柱实验研究表明:用N2和H2热处理均能有效提高活性炭对M IB的吸附能力。H2处理对M IB吸附能力的提高要好于N2。N2处理后的炭一旦长时间暴露在空气,吸附能力会有所降低。H2处理后的炭则能长期保持其处理能力。This research investigated methods to enhance adsorption of 2-methylisoborneol（MIB） by active carbon.Active carbon was modified via heat treatments in atmospheres of nitrogen and hydrogen.Rapid small-scale column tests indicated that heat treatment by H2 and N2 can both effectivly improve carbon＇s adsorption capacity for MIB.In general,H2-treated carbon performed better than those treated by N2.However,the improved adsorption capacity diminished if the N2-treated carbon was left exposed to air.In comparison,MIB adsorption capacity of active carbon after hydrogen-treated was stable.
