| Abstract: |
| A method was established for the determination of 14 kinds of phthalate esters（PAEs）in soil by accelerated solvent extraction and liquid chromatography. The result demonstrated that 14 PAEs can be separated completely with the recoveries range of 67.1%~128%, the accuracy RSD (n=6) range of 5.2%~15.0%. The method detection limits were from 0.021 to 0.034 mg/kg. The determination method has the advantages of simple operation and accuracy, it is practical in soil analysis. |
