유류 오염 토양 중 산화방지제 정성 분석을 통한 항공유(JP-8) 유종 판별 = Identification of Jet fuel (JP-8) in Petroleum Hydrocarbon Contaminated Soil through the Qualitative Analysis of Antioxidants

다국어 초록 (Multilingual Abstract)

Accurate analysis of petroleum hydrocarbons in soil is an important prerequisite for proper source tracking ofcontamination. Identification of petroleum compounds is commonly carried out by peak pattern matching in gaschromatography. However, this method has several technical limitations, especially when the soils underwent biological,physical and chemical transformation. For instance, it is very difficult to distinguish jet fuel (JP-8) from kerosene becauseJP-8 is derivatized from secondary reaction between chemical agents (e.g. anti-oxidants, antifreezer and so on) andkerosene. In this study, an alternative method to separately analyze JP-8 and kerosene in the petroleum hydrocarboncontaminated soil was proposed. Qualitative analyses were performed for representative phenolic antioxidants [2,6-di-tertbutylphenol (2,6-DTBP), 2,4-di-tert- butylphenol(2,4-DTBP), 2,6-di-tert-butyl-4-methyl phenol (2,6-DTBMP)] using atwo dimensional gas chromatograph mass spectrometer (2D GC×GC-TOF-MS). This qualitative analysis of antioxidantsin soil would be a useful complementary tool for the peak pattern matching method to identify JP-8 contamination in soil.
