固相萃取-气相色谱法测定地表水中五氯酚

Determination of pentachlorophenol in surface water by solid phase extraction and gas chromatography

建立了固相萃取-气相色谱法测定地表水中五氯酚的方法。HLB固相萃取小柱富集水样中待测物质,经二氯甲烷洗脱后,氮吹浓缩,采用气相色谱氢火焰离子化检测器进行分析。本方法具有操作简单快速、有机试剂使用量少、测定结果准确度和精密度高、方法检出限低等优点,适用于地表水中痕量五氯酚的测定。

The method established by solid phase extraction and gas chromatography determination of pentachlorophenol in surface water. HLB solid phase extraction column preconcentration of analytes, eluted with dichloromethane, nitrogen concentration by gas chromatography flame ionization detector is analyzed. This method has the advantages of simple operation, rapid organic reagent use less determination results, good accuracy and pre-cision, low detection limit, and suitable for determination of trace pentachlorophenol in surface water.
