摘　　要：建立了15种邻苯二甲酸酯类化合物的气相色谱-质谱(GC-MS)分析方法,并将其应用于饮料样品的测定。在对检测条件进行优化的基础上,通过提取特征离子进行检测,得到15种目标物的线性范围为5～10000μg/L,方法的检出限(S/N=3)为3～500μg/L;考察了各类饮料的提取方法,并在100μg/L、10000μg/L两个加标水平下对方法的可靠性进行评价,平均回收率为90%～110%(n=6),相对标准偏差(RSD,n=6)为0.58%～4.90%。该方法灵敏度高、精密度好、前处理过程简单、溶剂用量小、净化效果好,可用于饮料中邻苯二甲酸酯的快速准确分析。A gas chromatography mass spectrometric （GC -MS） method was developed for the determination of 15 phthalate esters in beverage samples. Under the optimum chromatography conditions and the selected ion monitoring （SIM） mode, calibration curves of 15 phthalate acid esters were linear in the range of 5 - 10000g/L, the detection limit ranged in 3 - 500g/L for 15 phthalate esters. The extraction method of PAEs in different drink was investigated, and the recoveries at two spiked levels ranged from 90% - 110% with RSDs of 0. 58% -4. 90% （n = 6）. The results demonstrated that the present method was sensitive, accurate, simple, reproducible, and could be applied in the determination of phthalate esters in different kinds of beverage.
