| Abstract: | After comparing different extraction methods and solvents for extracting phthalate esters, soil samples were extracted using ultrasonic with n-hexane/acetqne (V/V:2/1), then purified with sulphuric acid, analysed by GC-ECD. The spiked recoveries for DBP and DEHP were 83.5% and 93.1%,respectvely. The method has the characteristics of saving time and solvents, with good purification efficiency and low blank. |
