采用毛细管气相色谱测定2种邻苯二甲酸酯类化合物[邻苯二甲酸二丁酯（DBP）和邻苯二甲酸二异辛酯（DEHP）]。样品用正己烷浸泡，超声辅助提取，0.45μm滤膜过滤，进行气相色谱分析。气相色谱回收率为89.365%~117.875%，精密度RSD为0.26%~2.5%。结果表明，该方法简便、快速、灵敏，适用于食品塑料包装材料中邻苯二甲酸酯类增塑剂的测定。%The gas chromatography was taken to detect two kinds of phthalic acid ester compounds [butyl phthalate(DBP)andphthalate(2-ethylhexylester(DEHP)]. The sample was soaked in n-hexane, were extracted by ultrasonic,and analyzed by gas chromatography. The recovery rate of Gas Chromatography: 89.365 %-117.875%, the precision RSD ,0.26%-2.5%. Results showed that the method is simple, rapid, sensitive and suitable for food plastic packaging materials in the determination of phthalic acid esters plasticizer.
