| Abstract: | A method of liquid-liquid extraction-GC-MS/MS was established for the determination of pentachlorophenol and sodium pentachlorophenate in water.By optimizing the determination conditions,the method had good linearity in the range of 1.00μg/L to 500μg/L.The detection limit and the limit of quantization were 1.00μg/L and 5.00μg/L,respectively.The recoveries of blank samples spiked with three concentration levels of sodium pentachlorophenate ranged from 89.8%to 98.4%,and the RSDs ranged from 5.5%to 10.7%(n=5). |
