| 摘 要： | 目的建立了液相色谱-离子阱-飞行时间串联质谱法(liquid chromatography-ion trap-time of flight mass spectrometry,LCMS-IT-TOF)高通量快速测定聚对苯二甲酸乙二醇酯(polyethylene terephthalate,PET)塑料瓶中10种紫外吸收剂的方法。方法样品采用三氯甲烷浸泡,超声萃取,甲醇-乙腈混合液(3:2,V:V)辅助沉淀净化后用Shim-pack XR-ODS(50 mm×2.0 mm,1.6μm)色谱柱分离,0.1%甲酸水(V:V)和含0.1%甲酸的甲醇-乙腈混合液(3:2,V:V)为流动相进行梯度洗脱。采用电喷雾正离子模式监测,外标法定量。结果 10种紫外稳定剂在0.05~50μg/m L范围内线性关系良好,线性相关系数(r~2)均大于0.99;检出限为0.05~0.1 mg/kg;3个水平下的加标回收率为91.2%~103.4%;相对标准偏差(RSD)为1.2%~6.6%。结论该方法操作简便、快速、准确,可用于PET塑料瓶中10种紫外吸收剂的同时检测。
