The presence of Volatile organic compounds(VOCs) in indoor and outdoor air is of concern because these gases promote photochemical formation of ozone and other contaiminants and may have adverse effects on human health. Generally adsorption is used for removal of VOCs because of recovery and energy saving. Especially active carbon fiber(ACF) provide much faster adsorption kinetics compared with the granular adsorbents conventionally used because of their small diffusion distance in fiber. Thus, the application of ACF may lead to smaller adsorption units and effective recovery of valuable components.
