Functional groups on the surface of activated carbon fibers are most likely subjected to a wide range of inter- and intra-molecular interactions. In this study, metal-treated activated carbon fibers were transformed using hydrochloric acid. The adsorption behavior, SEM morphologies, and transitions of the functional groups of the metal-treated samples were compared before and after acid post-treatment. Adsorption isotherms are used to characterize the values of SBET, the pore structure, and the volumes of the metal-acttivated carbon fibers (ACFs) before and after acid post-treatment. From SEM studies, changes in the shapes and sizes of the metal particles were observed after the samples had been treated with acid. The types and quality of various functional groups were studied through examination of FT-IR spectra nad use of the Boehm titration method. Finally, the quantitative properties of the metal contents were also examined using EDX spectroscopy.
