| Abstract: | A method was established for detecting 2,4- diaminotoluene in Complex Food Bag. 2,4-Diaminotoluene was extracted by dichloromethane. Sodium chloride was used to decrease the solubility of 2,4-Diaminotoluene in water. Deriva- tive reagent and by-product were vacuum distillated. The treated sample was analyzed by GC--MS. The experimental condi- tions were optimized to produce following results： average recoveries75.0-94. 0%, RSD less than 10%, detection limit 0. 5 mg/kg. The method met requirements of quantitative analysis. |
