Abstract

Three commercial wood activated carbons for air purification were selected for static adsorption/desorption of formaldehyde. The influence of the pore structure, surface functional groups and particle size of the activated carbon on the static adsorption of formaldehyde, and temperature on the desorption were researched. The results show that surface functional groups of the three activated carbons are basically the same, have less effect on the adsorption of formaldehyde; approximate BET surface area, larger microporosity of activated carbon adsorption capacity of formaldehyde is larger; at the same condition, the smaller particle size of activated carbon, adsorption capacity of formaldehyde is larger; temperature is one of the key factor effect on formaldehyde desorption, the absorption equilibrium activated carbon desorption should be at not lower than 70oC.
