MTBE and other gasoline additives contained in gasoline are known to be a refractory substance resistant to biodegradation. As a method of removing these substances, a research of method using native microbes of polluted soil was progressed and among these, bio-degradation possibility under aerobic ...

BTEX의 특성은? | ) 이상을 구성하는 BTEX(benzene, toluene, ethylbenznen, o-, m-, p-xylene)는 주로 유류저장탱크와 다양한 산업공정으로부터 배출된다. BTEX는 다른 가솔린 성분 중에서 상대적으로 물에 대한 용해성이 크며, 인체에 유독하고, 특히, 대표적인 발암성 물질로 분류된다(Lee, 2005). | |
가솔린이란 무엇인가? | 가솔린은 원유 생산물의 대표적인 물질로 다양한 탄화수소로 구성되며, 연료 요구 성능 및 환경 규제기준에 따라 정제 시 그 성분함량이 조정된다. 가솔린의 18%(Wet. | |
BTEX의 오염 특징은? | 유류 탄화수소인 BTEX는 NAPLs (non-aqueous phase liquids) 상태로 지하에 존재한다. 대수층에서 소수성 물질로 존재하는 방향족 탄화수소는 토양에 흡착되어 오염을 악화시키고, 지하수의 오염원으로 오랜 시간 동안 존재하여, 질량변화가 매우 느리다. 반면에, MTBE 는 BTEX에 비해 수용해도가 더욱 높아 지하물질에 거의 흡착이 되지 않아 유동이 흡착에 의해 지연되기 어렵기 때문에 오염지역이 광범위하다. |
