摘要
经过系统研究,建立了以正已烷/丙酮(V/V:2/1)为溶剂,对土壤进行超声萃取,然后以浓H_2SO_4进行纯化的分析土壤中酞酸酯的方法。本方法具有省时、省溶剂、空白低及纯化效果好的特点,具有很强的实用性。
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.
