Abstract

Azo dyes constitute about 66% of all colorants and they are widely used in industries such as textiles, plastics, ceramics, cosmetics and food. However, due to the reductive cleavage of some azo dyes into carcinogenic aromatic amines, many countries have set concentration limits or have banned the use of these azo dyes. Selected aromatic amines that pose health risk to consumers were simultaneously determined by gas chromatography mass spectrometry. A good linearity in calibration plot was obtained for the analytes and the low relative standard deviations indicated high instrumental precision. A recovery test was performed to validate the extraction method and the results obtained were between 92–114%. The method was applied to the analysis of real samples and the concentrations of aromatic amines detected were below the 30 mg/kg limit set by regulatory authorities.

气相色谱-质谱法同时测定偶氮染料有害的芳香胺产物

摘要

偶氮染料约占所有着色剂的66％，它们被广泛用于纺织，塑料，陶瓷，化妆品和食品等行业。但是，由于某些偶氮染料被还原裂解成致癌的芳香胺，许多国家已经设定了浓度极限或禁止使用这些偶氮染料。同时通过气相色谱质谱法确定对消费者构成健康风险的选定芳香胺。分析物在校准图中具有良好的线性，相对标准偏差低表明仪器精度高。进行了回收测试以验证提取方法，所获得的结果在92–114％之间。
