Abstract:
The TiO 2 -activated carbon fiber (ACF) was successfully prepared by electrospinning and thermal treatment. The nanofiber was characterized by scanning electron microscopy (SEM), thermogravimetric-differential thermal analysis (TG-DTA), X-ray diffraction (XRD) and Brunner-Emmett-Teller method (BET). The results showed that the average diameter of ACF was in the range 200-500 nm, and the preoxidation temperature and carbonation temperature were 250°C and 500°C, and the anatase TiO 2 appeared in fiber after carbonation, and TiO 2 -ACF specific surface area was 1146.7 m 2 /g. The TiO 2 -ACF was used for adsorption of low concentration SO 2 . The results showed that the adsorption rate increased with an increase in SO 2 concentration, furthermore the adsorption rate increased with prolonged adsorption time, the high adsorption rate was 67.6% after 40 min. While temperature was below 60°C, the adsorption rate decreased as the temperature increased, however when temperature was above 60°C, there was a slight increase of adsorption rate as the temperature increased.
