The purpose of this research is to absorb and remove sulfur dioxide existing in the air by using ion exchange non-woven fabric. So we found out very appropriate condition of anionic exchange fabric scrubber by measuring amount of SO$_2$ adsorption under the atmosphere that concentration, velocity, and humidity was 100∼200 ppm, 0.6∼1.0 m/sec, and 30∼90 RH%, respectively. Ion exchange capacity of ion exchanger showed the maximum value, 3.75 meq/g at pH 4, and adsorption equilibrium time was the maximum value, 30 h when gas velocity was 0.6 m/sec, moreover, at 80$^{C}$, adsorption equilibrium time tended to decrease more than 10 h. When concentration was 200 ppm, while reaction speed between SO$_2$ and ligand of fibrous ion exchanger was getting faster, adsorption break point had a tendency to get faster as well. In addition, when relative humidity in the scrubber was 90%, adsorption efficiency was 7.6%/h that seemed to be 30% higher than 4.6%/h coming from the condition that relative humidity had been 30%, and it was totally absorbed under 5 wt% NaOH solution in 5 minutes.
