| 제목 | Adsorption Properties of PAN / Pitch Blend Nanofibers by Electrospinning Method |
| 초록 | Compared to granular and powdered activated carbon, activated carbon fibers (ACF) have many advantages such as high adsorption capacities, high mass transfer rates for both adsorption and desorption. It has been known that the porous structure and adsorption properties of ACF are highly influenced by the nature of the precursors and the method of activation. Electrospinning provides a simple and highly versatile method of fabricating nanofibers from a polymer solution at high voltage by using an electrostatically repulsive force and an electric field between two electrodes. It seems to be very interesting to investigate the preparation and adsorption properties of PAN / pitch blend nanofibers. However, experimental and theoretical adsorption studies of composite PAN / Pitch nanofibers have been very limited to date. In this study, ACF was fabricated by electrospinning the PAN and pitch dissolved in dimethylformamide. The samples were characterized by SEM, BET, and XRD. To understand the adsorption properties of ACF, the adsorption equilibrium and kinetics of two adsorbates were studied. Adsorption kinetics was evaluated by the pseudo-second-order model. |
