| Abstract: | The gas chromatography method was developed for the determination of 2,4-D isooctyl ester in water coupled with ECD detector. The separation was carried out on HP-5 column and was detected by ECD.The linear range of 2,4-D Isooctyl Ester was 0.010 to 5.0 mg· L^-1 ,the detection limit was 0.0001mg· L^-1,spike recoveries rate was 82.0%-93.2%,and the RSDs was 3.85%-4.25%.This method operated simple and detection effect of 2,4- D isooctyl ester in water was good. |
