摘要：

提出气相色谱-质谱联用仪同时测定文具中6种邻苯二甲酸酯类增塑剂的方法,以正己烷为溶剂,采用索氏提取法提取文具中6种邻苯二甲酸酯类增塑剂,采用外标法进行定量。该方法平均回收率为87.6%~103.1%,相对标准偏差为0.45%~4.17%,检出限分别为0.5 mg/kg(邻苯二甲酸二丁酯DBP),0.75 mg/kg(邻苯二甲酸丁苄酯BBP),0.75 mg/kg[邻苯二甲酸二(2-乙基)己酯DEHP],1.0 mg/kg(邻苯二甲酸二正辛酯DNOP),5.0 mg/kg(邻苯二甲酸二异壬酯DINP),5.0 mg/kg(邻苯二甲酸二异癸酯DIDP)。

Abstract: A method was proposed to determine the content of six kinds of phthalates in stationery by gas chromatography-mass spectrometer (GC-MS).Using n-hexane as solution, the sample was extracted with Soxhlet extraction method, and the content of six plasticizers was determined with external standard method.The average recovery varied from 87.6% to 103.1%, the relative standard derivation ranged from 0.45% to 4.17%.The limits of detection were 0.5 mg/kg(DBP), 0.75 mg/kg(BBP), 0.75 mg/kg(DEHP),1.0 mg/kg(DNOP), 5.0 mg/kg(DINP), and 5.0 mg/kg(DIDP) respectively.
