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 TiO2 광촉매의 doping 성분에 따른 비주류 담배연기 내의 CO, H2S, NH3, HCHO의 제거 효율을 확인하고자 하였다. 실험 결과, CO가 최대 78.37% 제거되었으며, TiO2 광촉매 공정이 CO 제거에 효과적인 것으로 확인되었다. 또한 CO, H2S, HCHO의 제거에 있어서 TiO2 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, H2S, NH3 and HCHO in a side-stream tobacco smoke using the doping component of TiO2 photocatalysts was confirmed. As a result, CO was removed up to 78.37%, which indicated that the TiO2 photocatalytic process is effective for CO removal. Also, the removal efficiencies of CO, H2S and HCHO were greatly affected by the amount of doped O and Si components of the TiO2 photocatalyst. In conclusion, the more doped O and Si components had, the higher removal efficiencies of harmful substances were achieved.
