硅藻土上 담배煙氣 吸着에 관한 硏究 = Adsorption of Cigarette Smoke on Diatomaceous Earth

국문 초록 (Abstract)

慶北 月城産 硅藻土를 時間別, 溫度別로 熱處理하여 芳香族 및 알콜 吸着指數를 求하고 이 硅藻土에 의한 담배煙氣中에 존재하는 有害成分의 吸着성능을 측정하였다.
硅藻土의 흡착능은 芳香族吸着指數로 決定하였으며, 表面에 對한 흡착選擇性은 알콜吸着指數에 의하여 測定하였다. 30∼40 mesh 硅藻土의 最適 活性化條件은 1000℃에서 2∼3時間이었다.
三重필터에 의한 담배煙氣中 有害成分은 二重필터에 의한 除去率보다 tar 13.9%, 니코틴 15.7%, 一酸化炭素 4.0%, 二酸化窒素 11.5%만큼 더 吸着除去되었다. 따라서 硅藻土를 熱處理함으로 低탈,低니코틴 담배製造用 필터充塡劑로 活用可能함을 알았다.

The Wal-Sung diatomaceous earth in Korea was thermally treated at different temperatures and time intervals, and its index of adsorption capacity was measured using alcohol and aromatics by AAI and EAI method.
The optimum activating temperature and heating time revealed 1000℃ and the range of 2∼3 hours. The cavity filled with the activated diatomaceous earth reduced about 13.9% tar, 15.7% nicotine, 4.0% CO, and 11.5% NO₂comparing with cellulose acetate filter tip. The above results showed that diatomaceous earth may be used as a filter additive to reduce the tar and nicotine delivery.
