Abstract

In this work, Rayon-based activated carbon fiber(KF-1500) was treated by HN $O_3$ and $H_2$S $O_4$ with different conditions. Specific surface areas(SSA, $S_{BET}$) of the treated activated carbon fibers were decreased by acidic treatment but, total surface acidities and surface functional groups were increased. In spite of the decrease of SSA, propylamin(PPA) adsorption and removal ability by activated carbon fiber(ACF) were increased by nitric acid treatment compared with the raw-ACF(KF-1500) and coconut based activated carbon. However, acidic treated activated carbon fibers were available to removal for various amines and contaminants by adsorption.n.
