HaoHan Chromatography (Shandong Applied Technology Development Co., Ltd.) uses GC-MS gas chromatography-mass spectrometry to determine the content of 2,4-diaminotoluene in composite food packaging bags. After leaching 2,4-diaminotoluene in boiling water, liquid-liquid extraction is performed using dichloromethane as the solvent. Sodium chloride is added to improve the extraction efficiency, and the concentrated sample is directly subjected to GC-MS quantitative and qualitative analysis. The experimental results show that the linear range is 0.002-0.01 mg/L, the linear equation is Y=5136+69.526X (r=0.9994), the detection limit is less than 0.002 mg/L, and the recovery rate is between 71% and 95%.
