| 摘 要： | 目的：建立二氨基甲苯残留的气相色谱一质谱检测方法。方法：沸水浸取样品中二氨基甲苯后，用甲苯进行液一液萃取，经三氟乙酸酐衍生化，再将衍生物进行GC—MS定性定量分析。结果：方法最低检出浓度为0．0002mg／L，相对标准偏差（RSD）为2．5％（n=6），样品加标回收率为98．11％～101．21％。结论：将GB／TS009．119—2003方法中的不足进行了一定的改良，用GC—MS方法检测复合食品包装袋是二氨基甲苯残留量，结果满意。 |

| Abstract: | Objective:To establish a method for determination of 2,4-Diaminotoluene residues by GC-MS.Method:2,4-diaminotoluene in samples was extracted with boiling water,and the water was liquid-liquid extracted with methylbenzene.Finally,2,4-diaminotoluene of methylbenzene was derivated with trifluoro-acetic anhydride and its derivative was used for determination by GC-MS.Results:The detection limits were 0.0002 mg/L,and RSD was 2.5%(n=6),the recoveries were between 98.11% and 101.21%.Conclusion:The established method is quite suitable for identification and quantization of 2,4-diaminotoluene in composite laminated food packaging bag,and the bugs of GB/T5009.119-2003 were improved. |
| Keywords: | 2 4 - Diaminotoluene GC - MS Dervivatization Composite laminated food packaging bag |
