| Abstract: | An analytical method for determination of chlorpyrifos in water by solid-phase extraction(SPE) and GC-FPD was developed,with linear range of 0.25～5.00mg/L,recovery rate of 94.2%,relative standard deviation(RSD) 2.5%,detection limit 0.25μg/L.The method which is sensitive,accurate and able to eliminate the interference is suitable for determination of trace chlorpyrifos in water. |
