| Abstract: | To present a rapid and sensitive method for analysis of phenoxyacid hebicides 2,4-D.MCPP. 2,4-DP, MCPA in urine; The four phenoxyacid herbicides in urine were analyzed by GC/MS/SIM with liquid-liquid extraetion and DCPA was used as internal standard,diethyl ether as liquid extraction, derivatization regent was n-butyl aleohol. The relative recoveries of the four herbicides were above 80%, the detection limits were below 5 ng/ml; The urine sample of rabbit poisoned by 2,4-D, MCPP were analyzed and the results showed that the method was sensitive and accurate. |
| Keywords: | phenoxy acid herbicides urine derivatization extraction gas chromatography -mass spectrometry（GC/MS） |
