Abstract
젖은 벽탑을 사용하여 30℃에서 물, 각 농도의 NaOH, CMC 및 NaOH-CMC 수용액에 의한 CO2의 흡수실헙에서 기-액접촉시간을 변화시켜 CO2기체의 흡수속도을 측정하였다.
실험결과는 침투설을 근거로 한 반응흡수이론에 의해 해석하였으며, 그 결과 반응촉진계수 β의 측정치가 CO2와 OH-와의 비가역 2차반응을 동반하는 흡수에 대한 Hikita 등의 근사이론식과 실험오차 ±8 %이내에서 일치하고 있다.
Power-law에 적용되는 비뉴톤액체에서의 반응흡수기구는 비뉴톤액체의 특성치를 첨가한 뉴톤액체에서의 반응흡수기구에 의하여 해석할 수 있었다.

The rate of absorption of carbon dioxide into water, aqueous sodium hydroxide, CMC（carboxymethy1 cellulose）, and sodium hydroxide-CMC has been measured by various changes of contact time between gas and liquid using a wetted-wall column at 30 ℃.
The experimental data were analysed by the penetration theory based on the gas absorption with second order irreversible chemical reaction CO2 and OH-.
The measured reaction enhancement factors were consistent with those predicted by the approximated equation derived by Hikita et al. within the range of ±8 % of experimental error.
The mechanism of gas absorption with reaction into Newtonian liquid could be also used in the case of Power-law liquids.
