The effects of attapulgite thermally activated at different temperatures, formaldehyde concentration and gas residence time on the formaldehyde removal efficiency were investigated. The reaction mechanism of formaldehyde on the surface of attapulgite particles was investigated by In-situ-diffuse reflectance infrared spectroscopy. The results show that attapulgite (Pal-250) thermally activated at 250℃ has an optimum formaldehyde removal rate. Oxygen enhances the removal of formaldehyde in the presence of Pal-250, indicating that the removal mechanism of attapulgite thermally activated for formaldehyde is physical adsorption and the catalytic mineralization process. The adsorbed formaldehyde can be partially mineralized into methylene dioxymehtylene, formate, carbonate and other species.
