Abstract
Breakthrough times of organic vapors on an adsorption column packed with activated carbon particles were measured under intermittent airflow conditions. Vapors were introduced into the column intermittently at intervals of between 10 minutes to 24 hours. The breakthrough times obtained under intermittent airflow conditions were compared with those under steady state ones. The results indicated that the breakthrough times of ethyl acetate under intermittent flow conditions were significantly shorter than those under steady states when the time interval was 24 hours. The breakthrough times of toluene under both conditions were not significantly different.
