The adsorption and penetration behaviour of 23 organic vapours on an a
ctivated carbon bed were studied varying the flow rate of the vapours
(V = 0.2, 0.4, 0.8 l cm(-2)-minute) and the bed depth (Z = 1.0, 2.0 cm
). An improved equation for predicting breakthrough time of organic va
pours and dry air mixture was proposed which provides a high level of
accuracy. (C) 1998 Elsevier Science Ltd. All rights reserved.
