采用气相色谱法测定皮革中的戊二醛含量,研究萃取条件、测试条件对检测结果的影响,优化检测条件和仪器分析条件,研究检测方法的检出限、回收率等。实验结果表明:戊二醛的回收率在82%以上。GC/MS方法检出限为4.0 mg/kg,GC-FID方法检出限为25 mg/kg,GC/MS法的检出限远远低于GC-FID。 The content of glutaraldehyde in leather was determined by gas chromatography. The effects of extraction conditions, test conditions on test results, optimization of test conditions and instrument analysis conditions, and the detection limits and recovery rates of the test methods were studied. The experimental results show that the recovery of glutaraldehyde is over 82%. The detection limit of GC / MS was 4.0 mg / kg. The detection limit of GC-MS was 25 mg / kg. The detection limit of GC-MS was much lower than that of GC-FID.
