Abstract
A dynamic adsorption device was designed for the study.Three types of harmful gases with high level in indoor air that were formaldehyde,benzene and toluene were selected as adsorbate.Its breakthrough curves were determined by gas chromatograph.The adsorption of activated carbon and zeolite were compared.The conclusion is that zeolite is better to adsorpt low concentration of formaldehyde and toluene and activated carbon is better to adsorpt low concentration of benzene.The adsorption of activated carbon is better than zeolite through the comparison of equilibrium adsorption capacity,breakthrough time and equilibration time.
