Abstract

Adsorption of low concentration formaldehyde on pitch-based, rayon-based, and PAN-based activated carbon fibers (ACFs) and an unactivated PAN-based carbon fiber (PAN-CF) was investigated by a dynamic method. The pore structure and surface chemistry of these samples were characterized by liquid nitrogen adsorption, elemental analysis, and X-ray photoelectron spectroscopy. Results revealed that the pore structure, especially surface chemical composition, greatly influence the formaldehyde adsorption. PAN- based ACFs showed the highest formaldehyde adsorption capacity because there are more abundant nitrogen-containing groups, especially pyrrolic, pyridonic, pyridinic, and quaternary on the surface. The breakthrough time and formaldehyde adsorption capacity of one kind of PAN-ACF were 361 min and 0.478 mmol/g, respectively.
