| Abstract: | A method for GC-ECD determination of deltamethrin in water was established.10 mL of water sample,previously added with 0.4 g of NaCl,was extracted by 5 mL of cyclohexane twice.The organic phase dried and concentrated,then determined by capillary column gas chromatography with electron capture detector(ECD) and quantified by external standard method.The results showed that the correlation coefficient was 0.999 8 in the linear range at 2.0～40.0 μg/L.The method detection limit(MDL) was 0.40 μg/L.Recovery and repeatability(relative standard deviations,RSD,n=5) were 97.0% and 13.9%,respectively.The method is rapid,precise and high efficient.It can be applied to the routine analysis of deltamethrin in water. |
