提出ＧＣ－ＦＣＤ分析方法测定水中微量五氯酚残留量。水样经萃取分离、衍生后，采用石油醚提取醋酸五氯酚酯，然后进入色谱柱，柱内填充２％ＯＶ－１７＋２％ＱＦ－１／ＣｈｒｏｍｏｓｏｒｂＷ－ＨＰ（８０～１００目），柱温２００℃，Ｎ＿２流量８０ｍＬ／ｍｉｎ，五氯酚酯３ｍｉｎ内出峰，最低检测浓度为０．１μｇ／Ｌ，各种样品回收率均在９０％以上，样品测试结果满意，可用于多种水体中微量ＰＣＰ残留量的测定。
The GC-FCD method was proposed for the determination of trace pentachlorophenol in water. The water sample was extracted and separated. After derivatization, petroleum ether was used to extract pentachlorophenate acetate. The column was then packed with 2% OV-17 + 2% QF-1 / ChromosorbW-HP ℃, N2 flow rate 80mL / min, pentachlorophenol peak within 3min, the lowest detection concentration of 0.1μg / L, the recovery rate of various samples are above 90%, the sample test results are satisfactory, can be used for a variety of water trace Determination of PCP residue.
