| Abstract: | Microwave was used to extract five phthalatic acid esters in sediment with acetonitrile solvent.After the purification process by a florisil column the solution was passed to the gas chromatography-mass spectrometry for analysis.The testing was performed with the detection limit 0.030 mg/kg,while in precision testing the relative standard deviations was below 2% with recovery rate staying between 72.5% and 108.0%. |
