摘要
探索了PVC人造革中邻苯二甲酸酯类增塑剂的提取和检测方法。分别采用二氯甲烷、三氯甲烷、正己烷为提取溶剂，利用超声波提取以及索氏提取的方法，对PVC人造革中16种邻苯二甲酸酯类增塑剂进行提取，比较不同的提取溶剂在不同的提取方式下的提取效率。用气相色谱-质谱法（GC—MS）的分段选择离子监测（SIM），对样品中的邻苯二甲酸酯（PAEs）的检测方法进行了优化。结果表明：用正己烷为提取溶剂采用索氏提取5h为最优化的提取方法，该方法的平均回收率为83．2％-106．3％，相对标准偏差为2．0％～6．1％。该方法操作简单，灵敏度较高，适用于PVC人造革中的邻苯二甲酸酯类物质的分析检测。
The extraction and determination of 16 phthalate ester plasticizers in artificial leather was investigated. Artificial leather was extracted by automated soxhlet extraction method and ultrasonic extraction method with methylene dichloride, chloro- form and normal hexane as the solvent respectively. The extraction efficiencies of different extraction method and different solvent were compared. Phthalates in artificial leather were transferred to capillary column for GC - MC in selective ion monitoring mode （SIM）. The result shows that PAEs can be effectively extracted with normal hexane under soxhlet extraction for 5 hours. The re- coveries range from 83.2% to 106.3 %. Relative standard deviation range from 2.0% to 6.1%. The developed analytical method is rapid and accurate, and suitable for the determination of PAEs in artificial leather.
