Zusammenfassung: | The simultaneous analysis of alkylphenols, chlorophenols and bisphenol A in biota samples was performed by gas chromatography-mass spectrometry-selected ion monitoring mode. The phenols were extracted from sample with organic solvent and Forisil and Silica columns for clean-up procedure were compared. Recovery studies were performed at 1-ppm level of phenols added to each biota sample. Their recoveries ranged between 83 and 116% with coefficient of variations of 2.4-11.9%. To improve the detection limits of phenols, trimethylsilyl (TMS) derivatization was applied. The gas chromatographic properties of free phenols and TMS derivatized phenols were also investigated. 생물시료 중 존재하는 알킬페놀류, 클로로페놀류 및 비스페놀 A의 동시분석을 기체크로마토그래피-질량분석기-선택이온검색법에 의해 수행하였다. 시료 중 페놀류는 유기용매로 추출하고 정제과정은 Florisil과 silica 컬럼을 비교분석하였다. 회수율 실험은 각 생물시료에 1-ppm 정도를 첨가하여 수행하였다. 이들의 회수율은 83-116% 정도로 나타났고, 표준편차는 약 2.4-11.9%로 나타났다. 페놀류의 검출한계를 증진시키기 위하여, trimeaylsilyl(TMS) 유도체 방법을 도입하였다. 유도체화 시키지 않은 페놀과 TMS 유도체화된 페놀류의 기체크로마토그래피 성질을 연구하였다. |
