Determination of photoinitiators in printing inks used in food contact materials

建立了食品接触材料表面印刷油墨中光引发剂(PIs)二苯甲酮(BP)、4-甲基二苯甲酮(MBP)、对二甲氨基苯甲酸乙酯(EDAB)、N,N.二甲氨基苯甲酸异辛酯(EHDAB)和1-羟基环己基苯基甲酮(Irgacure 184)的气相色谱-质谱(GC-MS)分析方法.样品以乙酸乙酯为萃取溶剂进行索氏提取,萃取溶液经净化分离和富集以后,以5%苯基-95%甲基聚硅氧烷为固定相(DB-5MS),采用选择离子扫描(SIM)方式对上述5种PIs进行了定性和定量分析.5种PIs在5.0～200.0 μg/L范围内的线性关系良好(R<'2>>0.999 5),在2种浓度的添加水平下,回收率为66.7%～89.4%,相对标准偏差<10%.方法的定量限为0.0017～0.0036 mg/dm<'2>.该方法的样品前处理过程简单,易操作,适用于常规进出口食品接触材料表面印刷油墨中PIs的快速检测.
