초록

흡연으로 발생되는 담배연기는 주류 연기와 비주류 연기로 구분된다. 담배연기 중 실내로 확산되는 연기의 대부분은 비주류 연기이며, 비주류 연기의 유해물질 농도는 주류 연기의 농도보다 2~3배 높다. 본 연구에서는 $TiO_2$ 광촉매의 doping 성분에 따른 비주류 담배연기 내의 CO, $H_2S$, $NH_3$, HCHO의 제거 효율을 확인하고자 하였다. 실험 결과, CO가 최대 78.37% 제거되었으며, $TiO_2$ 광촉매 공정이 CO 제거에 효과적인 것으로 확인되었다. 또한 CO, $H_2S$, HCHO의 제거에 있어서 $TiO_2$ 광촉매에 doping된 O, Si 성분에 의해 영향을 크게 받는다. 결론적으로, doping된 O, Si 성분이 많을수록 유해물질 제거효율이 높다.

Tobacco smoke emitted during smoking is divided into a main-stream and side-stream smoke. Most of the tobacco smoke that spreads to a room while smoking is a side-stream one. The side-stream tobacco smoke is two to three times more harmful than that of the main-stream tobacco smoke. In this study, the removal efficiency of CO, $H_2S$, $NH_3$ and HCHO in a side-stream tobacco smoke using the doping component of $TiO_2$ photocatalysts was confirmed. As a result, CO was removed up to 78.37%, which indicated that the $TiO_2$ photocatalytic process is effective for CO removal. Also, the removal efficiencies of CO, $H_2S$ and HCHO were greatly affected by the amount of doped O and Si components of the $TiO_2$ photocatalyst. In conclusion, the more doped O and Si components had, the higher removal efficiencies of harmful substances were achieved.
