摘　　要：在纺织品的生产和销售过程中是否应用了日用消费品法规中禁用的偶氮染料是可以检测出来的。织物样品用化学助剂处理,经过还原裂解出来的胺类化合物用高效液相色谱/二极管阵列检测器(HPLC/DAD)、薄层层析(TlC、HPTLC)/以密度计定量、毛细管气相色谱/火焰离子化检测器或质量检测器(GC/FID或MSD)或毛细管电泳/二极管阵列检测器(CE/DAD)方法来测定。胺类化合物的鉴别必须使用至少两种不同的色谱分离方法,以避免由于干扰物质的存在而导致错误的鉴别结果。Whether the azo dyes forbidden by the consumer goods ordinance were used in textiles manufacturing and retailing can be detected. The sample will split into arylamines under reductive conditions after treated with chemicals. The methods used to determine the arylamines are as follows: HPLC/DAD, TLC/HPTLC,GB/ID or MSD and CE/DAD. Two or more chromatography should be applied for the impurities might cause deviation.
