제목 Effects of SO2 gas adsorption properties of N2 plasma treaed activated carbon fiber
초록 The mechanisms of the SO2 gas adsorption properties of activated carbon fibers were studied based on surface treatment. The surfaces of the activated carbon fibers (ACFs) were modified by plasma treatment using N2 gas to enhance the adsorption of SO2 by the fibers based on the effects of the nitrogen functional groups introduced on the surface. Nitrogen functional groups were effectively introduced onto the surfaces of the ACFs based on the semi-introduction with SO2 molecules, and they attached themselves to the pores of the ACFs as the flow rate of N2 gas increased. The nitrogen functional groups, on the surfaces of the ACFs played an important role in guiding SO2 into the micropores via the attractive forces experienced by the electrons in the SO2 molecules.
