摘　　要：目的建立气相色谱质谱法同时测定食品包装行业用UV油墨中11种光引发剂的方法。方法通过甲醇萃取油墨中的光引发剂,离心过滤后由气相色谱质谱仪测定11种光引发剂的含量。结果11种光引发剂在0.10~5.0 mg/L范围内线性关系良好(r^2≥0.995),在低、中、高3个添加水平下,回收率在88.5%~100.5%,重复性相对标准偏差(n=6)为3.3%~6.5%,检出限为0.03 mg/L。结论该方法具有操作简单、响应良好、快速分析等特点,能够满足同时测定食品包装行业用UV油墨11种光引发剂的分析要求。Objective To establish a method for simultaneous determination of 11 photoinitiators in UV inks used in food packaging industry by gas chromatography-mass spectrometry.Methods The photoinitiators in ink were extracted by methanol,and the contents of 11 photoinitiators were determined by gas chromatography-mass spectrometry after centrifugal filtration.Results Totally 11 photoinitiators had a good linear relationship in the range of 0.105.0 mg/L(r^2≥0.995).Under the addition levels of low,medium and high,the recovery rates were 88.5%100.5%,and the relative standard deviations of repeatability(n=6)were 3.3%6.5%,and the limit of detection was 0.03 mg/L.Conclusion This method has the characteristics of simple operation,good response,fast analysis,etc.,and can meet the analytical requirements for simultaneous determination of 11 photoinitiators for UV inks used in the food packaging industry.
