Abstract
In this paper, impregnated activated carbon fiber (IACF) was manutactured to pitch-based activated carbon fibers(ACF) with potassium hydroxide (KOH) by using wet impregnation method to raise mitrogen oxides (NOx) adsorptivity. The properties of IACF were observed using EPMA, TGA and DSC and NOx adsorptivity was observed at high and low temperature. Before and after adsorption was analyzed using ToF-SIMS for examine surface characterization of adsorbed NOx. The results showed that the better adsorptivity appeared for increasing KOH ratio. So, NOx adsorptivity showed result that is proportional between KOH and the adsorbed amount. On the other hand, adsorbent that manufactured without washing was better NOx adsorptivity than adsurbent that manufactured with washing. The increased but NO2 ratio decreased according as KOH ratio increases. NOx was confirmed through surface analysis that remain in NO2-and NO3-rorm on IACF surface.
