PAHs commonly found in industrial sites such as manufactured gas plants (MGP) are potentially toxic, mutagenic and carcinogenic, and thus require immediate remediation. In-situ chemical oxidation (ISCO) is known as a highly efficient technology for soil and groundwater remediation. Among the several...

다환방향족탄화수소(polycyclic aromatic hydrocarbons, PAHs)란? | 두 개 이상의 방향족 고리를 가지고 있는 다환방향족탄화수소(polycyclic aromatic hydrocarbons, PAHs)는 소수성 유기 오염물질로 화학연료나 유기물의 불완전 연소시 부산물로 발생하는 물질이다. PAHs는 강한 독성, 생물 농축성, 난분해성, 잔류성이 있어 인체 및 환경에 장기적인 피해를 유발한다. | |
PAHs의 특징은? | 두 개 이상의 방향족 고리를 가지고 있는 다환방향족탄화수소(polycyclic aromatic hydrocarbons, PAHs)는 소수성 유기 오염물질로 화학연료나 유기물의 불완전 연소시 부산물로 발생하는 물질이다. PAHs는 강한 독성, 생물 농축성, 난분해성, 잔류성이 있어 인체 및 환경에 장기적인 피해를 유발한다. 토양의 주요 PAHs 오염원은 유류저장 시설, 폐침목의 크레오소트, 코크스 제조공정 등에서 배출되는 유기화합물이며, 특히 제조 가스 플랜트(manufactured gas plant, MGP) 부지에서의 PAHs 오염 처리가 연구되고 있다(Chen et al. | |
적정량의 철을 주입하거나 철이 안정적으로 반응할 수 있도록 하는데에는 어떤 방법을 쓸 수 있는가? | , 2012) 적정량의 철을 주입하거나 철이 안정적으로 반응할 수 있도록 하는 것이 중요하다. 킬레이트제를 주입하여 철 이온의 침전을 막아 안정성을 높이거나(Tan et al., 2004; Zou et al., 2013) 하이드록실아민과 같은 환원제를 주입하여 Fe3+을 다시 Fe2+로 환원시켜(Wu et al., 2015) 과황산 산화 활성을 높힐 수 있다. |
