Abstract

The simultaneous analysis of samples, 16 organic pesticides in water among 129 priority pollutants listed by EPA, was performed by GC-ECD (electron capture detector) and GC/MS-SIM (selected ion monitoring). Two extraction procedures, liquid-liquid extraction (LLE) and solid-phase extraction (SPE), were studied as an extraction and concentration method. Accuracy and precision of the methods were measured by the calculation of mean recovery and mean relative standard deviation. Finally, the detection limits, the experimental limitations, and prospects were discussed.

미국의 환경청이 지정한 129종의 priority pollutants 중 16종의 유기살충제를 대상물질로 선정하여 수질시료 중의 극미량 분석방법을 연구하였다. 분석방법으로는 기체크로마토그래프-전자포획 및 기체크로마토그래프/질량분석기-SIM(selected ion moitoring)법을 검출방법으로 정하고, 시료용액의 추출 및 농축방법으로는 용매추출법(liquid-liquid extraction)과 고체상 추출법(solid-phase extraction)을 비교 연구하였다. 각 화합물들의 회수율, 상대표준편차 및 검출한계 등을 측정하여 EPA 분석법을 대체할 수 있는지의 가능성을 조사하였다.
