Abstract

본 연구에서는 초산화칼륨이 포함된 화학 폐를 이용하여 이산화탄소를 산소로 전환시켰다. 우선 초산화칼륨을 수산화칼슘과 혼합하여 초산화칼륨의 반응성을 낮추었다. 기제조한 수산화칼슘-초산화칼륨 혼합물을 수분제거에 용이한 실리콘 고분자 매트릭스에 여러 가지 비율로 분산시켜 화학 폐를 제조하였다. 일반적으로 화학 폐에 있는 초산화칼륨의 양이 많아질수록 변환되는 이산화탄소와 발생되는 산소의 양이 증가하였다. 후리에 적외선 분광기 분석결과 화학 폐에 분산되어 있는 규소-산소의 단일결합이 1,050 cm^(-1)에서 나타났다. 규소-산소 단일결합의 흡수도는 화학 폐에 있는 규소고분자의 함량이 높을수록 높았다. 본 실험결과는 이산화황이나 이산화질소같은 산성 가스의 전환에도 이용될 수 있음을 보여준다.

This study demonstrates the use of a chemical lung containing potassium superoxide to convert carbon dioxide in air to oxygen. In order to reduce its extremely high reactivity, potassium superoxide was first mixed with calcium hydroxide and then combined at various ratios with polysiloxane. Silicone polymer used here served as both a water repellent and the polymer matrix. In general, the amount of carbon dioxide captured as well as that of oxygen produced_x000D_ increased as the proportion of potassium superoxide in the chemical lung increased. FT-IR spectroscopy revealed that the Si-O bond in chemical lung appeared at 1,050 cm^(-1) and absorbance of chemical lung containing higher amounts of silicone was higher than that of chemical lung containing lower amounts. These results indicate that such a chemical lung may also be a useful sorbent for other acid gases, such as sulfur oxides and nitrogen oxides.
