Effects of E-Beam Irradiation on the Adsorption Behaviors of Activated Carbon Fibers for Chemical Protective Overgarment |
| 초록 |
Activated carbon fibers (ACF) were modified via e-beam irradiation in various gas atmospheres for use as an adsorbent of a chemical protective overgarment. E-beam irradiation was performed at 50 to 300 kGy. The N2 adsorption isotherm characteristics were measured at 77K. Brunauer-Emmett-Teller, Barrett-Joyner-Halenda, and non-local density functional theory equations were used to calculate pore characteristics. The surface functional groups of ACF were analyzed by a Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. The adsorption capacities of the ACF were measured by breakthrough experiments in the gas phase (150 g/mL of 2-CEES, DMMP, DFP in N2 balance). From the result, the e-beam irradiation on the ACF caused significant changes of surface functional groups without the deformation of pore characteristics. It was also found that the toxic gas removal ability of the ACF enhanced according to the surface treatment conditions. |
