摘要
采用微波辅助萃取气质（GC/MS）联用技术测量PVC中的PAEs检测方法,选择了邻苯二甲酸二正丁酯（DBP）、邻苯二甲酸苯甲基丁基二酯（BBP）、邻苯二甲酸二异辛酯（DEHP）、邻苯二甲酸二辛酯（DNOP）4种标物进行溶剂萃取、准确度、精密度以及方法检出限等多方面的研究。4种标物的方法检出限均在0.2-0.6μg/kg,精密度为3.16%-7.45%,回收率为91.3%-96.1%。该方法操作简便、准确,具有较好的实用性。
A method was developed for the determination of phthalate esters（PAEs） in polyvinylchloride （PVC） by GC-MS and microwave-assisted extraction techniques. DBP,BBP,DEHP and DNOP as the reference standards were investigated （microwave extraction,RSD,accuracy,detection limits etc. ）. Detection limits of the four compounds were between 0. 2 and 0. 6 μg/kg, respectively. The recovery varied from 91.3% to 96.1% ,and RSD were between 3.16% and 7.45%. The determination method with the advantages of simple operation and accuracy is practical.
