摘　　要：采用高效液相色谱法测定了染色纺织品和皮革中的禁用偶氮染料。对国家标准SN／T1045．1—2002进行了修改与完善，优化了芳香胺的提取溶剂为二氯甲烷和甲基叔丁醚（体积比1：3），净化试剂为Na8SiW11O39,同时液相色谱固定相由C8改为C18,获得了很好的分离效果，实现了23种芳香胺的同时分离检测。除2，4-二氨基甲苯外，对空白样品的加标回收率为80％～115％，相对标准偏差小于7．5％。该方法简便、快速、灵敏，满足国内外生态纺织品标准及法规限量的新要求。A high performance liquid chromatography （HPLC） method was developed for the determination of banned azo colorants in dyes textiles and leather products based on the modification of National Standard of SN/T 1045.1 -2002. The aromatic amine in samples were prepared by using dichloromethane and methyl tertiary-butyl ether（MTBE）（ 1 ： 3, by volume） as extraction solution and Na8SiW11O39 as purification agent. The extract was separated on C18 instead of C8 by using methanol - phosphate buffer as a mobile phase at flow rate of 0. 5 mL/min. The quantitative analysis was performed by a ultraviolet detector. The result indicated that 23 azo colorants were successfully separated. Excepting 2, 4-toluylenediamine, the average recoveries of 22 azo colorants varied from 80% to 115% with RSDs less than 7.5%. The method was simple, rapid and accurate, and was applied in the determination of aromatic amine in blue textile and red brown dyed leather samples with satisfactory results.
