Abstract

연무의 생성과정을 다음과 같은 전제 아래 연구하였다. 즉 대기 중에서 이산화황과 이산화질소가 반응할 때, 수분 또는 안개가 존재하면 초기단계에서는 태양광선에 의하여 니트로실황산이 생성되며 이것이 분해하여 황산을 만든다. 즉,
SO2*⁢H2O → H2SO3
H2SO3⁢NO2* → HOSO2ONO
HOSO2ONO → H2SO4⁢HNO3
이때 생긴 질산은 유기과산화물과 반응하여 과산화니트로화합물을 만든다. 결과적으로 황산화물, 질소산화물, 유기산화물, 니트로화합물 및 산화제의 혼합물은 대기 중에서 서로 작용하여 스목현상을 일으킨다. 이상과 같은 가정하에서 실험한 바 예기하였던 결과를 얻었다. 그리고 서울시내의 대기오염도를 측정하였던 바 황산화물의 오염도가 질소산화물보다 심하다는 사실을 알았다.
The formation of smog was studied on the basis of the following hypothesis : when sulfur dioxide and nitrogen dioxide react each other in the atmosphere, nitrosyl-sulfuric acid will be formed at the initial stage by solar radiation in the presence of moisture or fog and then sulfuric acid will be formed by the decomposition of nitrosyl-sulfuric acid. That is,
SO2*⁢H2O → H2SO3
H2SO3⁢NO2* → HOSO2ONO
HOSO2ONO → H2SO4⁢HNO3
The nitric acid generated by the above reaction will react with organic peroxide and forms nitro peroxide compounds. Finally, the mixture of sulfur oxide, nitrogen oxide, organic peroxide nitro-compounds and oxidant will cause the formation of smog. A series of experiments have been performed and the results supported the above hypothesis as expected. In addition, a separate study has been carried out with regards to the air pollution in Seoul to confirm that sulfur oxide was more serious than nitrogen oxide.
