초록

지표수 중에 GC-MS에 의한 25개 준휘발성유기물질을 동시에 분석하는 방법을 개발하였다. 1.0 L의 물 시료를 분액깔대기 안에 넣고 NaCl로 포화시킨 다음 40 mL methylene chloride로 두 번 추출하였다. 이 방법은 0.01-800 ng/L 범위의 직선성을 보였고 15% 이내의 정밀도를 보였다. 확립한 방법을 사용하여 금강물 16개 시료를 분석한 결과 준휘발성유기화합물이 0.02-96.8 ng/L의 농도범위로 검출되었으며 측정값은 US EPA 또는 독일에서 확립한 준거치 이하의 값을 보였다. 이 측정방법은 지표수에서 SVOCs 대한 국가모니터링사업에 사용할 때 효율적인 것으로 판단된다.

A gas chromatography-mass spectrometric (GC-MS) method was developed for determining 25 semivolatile organic compounds in water. A 1.0 L water sample was placed in a separatory funnel and saturated with NaCl, and the solution was extracted two times with 40 mL of methylene chloride. Under the established condition, the linear quantification range was 0.02-800 ng/L and the relative standard deviation was less than 15%. The method was used to analyze 16 surface water samples collected from various regions in Gum-River. The samples revealed SVOC concentrations in the range of 0.02-96.8 ng/L. Maximum concentrations of VOCs detected were not exceeded the EPA or Germany guidelines in any of the samples. The developed method may be valuable for monitoring SVOCs in water.
