Abstract
Pentachlorophenol (PCP) is a representative compound of chlorophenol derivatives which are especially toxic and potentially carcinogenic compounds in the priority pollutant list of the EPA (Environmental Protection Agency, USA). The aim of this study was to investigate an analysis method of PCP in infinitesimal quantity retained in paper. PCP in paper was pretreated by solid phase extraction (SPE) in a phenyl cartridge. The extracted sample was acetylated or silylated and analyzed with GC/MS-SIM. The detection sensitivity of silylated PCP was improved significantly when compared with those of PCP itself and acetylated PCP. As a test specimen, an office paper and a wallpaper were used.
Pentachlorophenol (PCP)은 독성이 강한 발암성 물질로 미국환경청(Environmental Protection Agency, USA)이 정한 대표적인 환경호르몬이다. 본 연구에서는 종이 중에 함유된 극미량의 PCP 측정을 목적으로 하였다. 종이의 전처리는 고상추출법(SPE)을 이용하였고 분석을 위해 PCP를 유도체화시켜 gas chromatography/mass spectroscopy-selected ion monitoring (GC/MS-SIM)으로 분석하였다. GC/MS-SIM의 분석 결과 실릴화 PCP의 분석감도가 증가되었다. 본 실험에서는 실험군으로 사무용지와 벽지를 사용하였다.
