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...
