In this study, the adsorption capacity of formaldehyde was analyzed by using Activated Carbon and five types of synthetic zeolite. The experiments were conducted according to 2,4-dinitrophenylhydrazine (DNPH) derivatization and high pressure liquid chromatography (HPLC) methods for analysis of formaldehyde. The adsorption capacity of formaldehyde was discussed by outflow/inflow of concentration, amount of adsorption per gram of adsorbent, averaged removal rate and economic evaluation. Total amount of adsorption per gram of adsorbent decreased steadily for increasing the fill amount of adsorbent. The most amount of adsorption was represented for Beta Zeolite Fe, but the economic evaluation was relatively high for Zeolite A. Activated Carbon showed relatively superior persistence of adsorption in the adsorption experiment for 200 minutes. The stability of adsorption was evaluated to relatively superior for Zeolite X in the repeated experimental results of the 20 minutes adsorption for formaldehyde. This study suggested that the selective use of various synthetic zeolite may be useful for formaldehyde removal considering adsorption capacity and economic feasibility.
