| Abstract: | A gas chromatography with electron capture detection(GC-ECD)method for Direct determination without of derivatives of Sodium pentachlorophenol in the water.Target compounds in samples extracted with ethyl acetate and for GC determination.The linear range were good relationship of Sodium pentachlorophenol in 0.35~400μg/L,correlation coefficient was 0.9992 for Sodium pentachlorophenol.At spiked level 1.0、5.0、10.0μg/L for Sodium pentachlorophenol,recoveries were between 95.8%~98.7%,with relative standard deviations was lower 3.6 %.The limit of detection(S/N=3) and limit of quantification(S/N=10) of Sodium pentachlorophenol were 0.35μg/L and 1.0μg/L,respectively. |
