摘要
建立了学生用塑料书套中6种常见邻苯二甲酸酯(PAEs)类增塑剂的快速检测方法。以二氯甲烷为萃取溶剂,通过超声萃取对样品中的PAEs进行提取,随后采用气相色谱-质谱联用法(GC-MS)进行检测。结果表明:市售聚氯乙烯(PVC)材质书套中普遍检出了高浓度PAEs,其主要成分为邻苯二甲酸二(2-乙基)己酯(DEHP)。该检测方法提取效率高,线性范围较宽,回收率高且重现性好。
A rapid determination method for six kinds of common phthalate esters（PAEs） in student plastic slipcase was established,the PAEs were extracted from samples by ultrasonic extraction with dichloromethane and analyzed by gas chromatography-mass spectrometry（GC-MS）.The results show that high concentration PAEs are found in polyvinyl chloride（PVC） plastic slipcase that available in the market,and its main ingredient is di-2-ethylhexyl phthalate（DEHP）.And the method shows high extraction efficiency,higher recovery,wide linear range and good reproducibility.
