Activated Carbon Fibers from Acetic Acid Lignin

Abstract

Activated carbon fibers (ACF's) were prepared from acetic acid lignin-based carbon fibers by steam activation. The ACF had excellent properties, such as more rapid adsorption rate and higher iodine and methylene blue adsorption capacities, as compared to a commercially available activated carbon. The adsorption mechanism of ACF was quite different from that of activated carbon (AC). as supported by the micropore distribution profiles.
