摘　　要：建立了一种测定含聚酯纺织品中禁用偶氮染料的预处理新方法，所得结果能代表实际分解的芳香胺量。该方法加标回收率为77．5％～102．4％，RSD为0．68％-3．51％，在S／N=3条件下，方法的检出限为O．03—0．39mg／kg。该方法操作简单、环保，具有良好的重演性和准确性，可有效应用于含聚酯纺织品中可分解芳香胺的快速检测。A new pretreatment method for determination of banned azo dyes in polyester-containing textiles is established. The results represent the actual amount of decomposition of aromatic amines. The average recoveries are 77. 5% -102.4% with 0.68% -3.51% of RSD. At the condition of S/N （signal/noise） =3, the detection limits vary from 0.03 mg/kg to 0.39 mg/kg. This method features accuracy and good reproducibility, and can be effectively applied to quick detection of banned azo dyes in polyester-containing textile.
