摘　　要：针对皮革4-氨基偶氮苯的国标检测方法GB/T 33392—2016测试过程进行优化研究,通过同时进行偶氮染料和4-氨基偶氮苯的检测、压缩空气吹干正己烷代替过夜晾干缩短其检测流程,同时优化仪器色谱分析方法,减少样品分析时间,以满足大批量样品高效快速化检测需求;通过气质联用仪和液相色谱仪标准曲线和测试重复性比较发现,使用液相色谱法作为定量方法准确性更高。In this paper,the test process of the national standard detection method GB/T 3392-2016 for leather 4-aminoazobenzene was optimized,and the detection process was shortened by the simultaneous detection of azo dyes and 4-aminoazobenzene,the compressed air blows dry n-hexane instead of overnight drying,and the instrument chro-matographic analysis method was optimized to reduce the sample analysis time,so as to meet the needs of efficient and rapid detection of large quantities of samples.Comparison of GC standard curves and test repeatability between GC and GC found that the use of LC as a quantitative method was more accurate.
