초록

미국 환경청이 지정한 129종의 priority polluatants 중 40종의 비휘발성 염기/중성 유기화합물을 대상물질로 선정하였다. 분석방법으로 초음파 추출법(sonication extraction)과 Soxhlet 추출법(Soxhlet extraction)을 이용하여 토양에 있는 유기물을 추출 및 농축하여 기체크로마토그래프/질량분석기-SIM(selected ion monitoring)법으로 검출하였다. 표준물질이 첨가된 토양시료에 두 추출법을 적용하여 회수율을 구하고 정확도, 정밀도 및 검출한계를 측정하여 미량 분석의 가능성을 조사하였다.

This study was aimed at the detection of 40 semi-volatile organic base/neutral compounds from soil among 129 priority pollutants listed by EPA. Two extraction procedures, sonication extraction and Soxhlet extraction, were studied as a extraction and concentration method for priority pollutants in soil. Extracts were analyted by GC/MS-SIM(selected ion monitoring). The analytical methods were tested by standard compounds spiked into blank soil. Accuracy and precision of the methods were measured by calculation of mean recovery and mean relative standard deviation. And the method detection limits were estimated.
