최근, 가솔린 첨가물인 Methyl tert-butyl ether (MTBE)가 음용수로 사용되는 대수층으로 방출되는 것에 대해 상당한 관심이 되고 있다. MTBE는 친수성이고, 가솔린 유출과 새고 있는 저장탱크 누출에 의해 환경에 노출되어 물과 쉽게 섞이게 된다. 본 논문에서는 실험실 규모 반응기내에서 MTBE 용액의 탈기 및 오존산화반응을 연구하였다. 계산한 질량 전달율(N)은 $1.24{\times}10^{-6}\;mol{\cdot}sec^{-1}$으로 나타났다. MTBE의 오존산화반응 실험결과 COD와 TOC는 각각 8.3%와 6.5% 감소하였고 BOD/COD는 0.03으로 큰 변화가 나타나지 않았다. 유사 1차 반응속도 상수는 $3.75{\times}10^{-5}\;sec^{-1}$으로 나타났다. 활성화 에너지는 4.80 kcal.mol-1로 나타났다.

In recent years, there has been considerable concern over the release of methyl tert-butyl ether (MTBE), a gasoline additive, into the aquifers used as potable water sources. MTBE readily dissolves in water and has entered the environment via gasoline spills and leaking storage tanks. In this study air stripping and ozonation of MTBE in aqueous solution were performed in a laboratory scale batch reacter. The mass transfer rate (N) was evaluated and a values about $1.24{\times}10^{-6}\;mol{\cdot}sec^{-1}$ was found. In the ozonation of MTBE a 8.3% decrease of the COD and a 6.5% decrease of the TOC lead to BOD/COD = 0.03. The peudo first-order rate constants of the ozonation of MTBE was $3.75{\times}10^{-5}\;sec^{-1}$. The resulting Ea of 4.80 kcal;mol-1 was observed for molecular ozone reactions.
