摘　　要：本文研究发现如果纺织品染色中使用了颜料红112,在用GCMS法测试纺织品种偶氮染料时,用2,4,5-三氯苯胺作为内标定量分析就容易产生假阴性干扰,影响禁用偶氮染料检出项的检测结果。This study found that if pigment red 112 is used in textile dyeing,when using GCMS method to test textile azo dyes,using 2,4,5-trichloroaniline as an internal standard for quantitative analysis will easily produce false negative interference,which will affect the prohibition of couples.Test results of nitrogen dye detection items.
