摘要
禁用偶氮染料会释放致癌性芳香胺物质,危害人体健康.纺织品禁用偶氮染料的检测是国家强制性标准GB 18401-2010和GB 31701-2015中明确要求的项目,也是出口时重点关注的检测项目.从标准物质、前处理的回收率、同分异构体的分离和假阳性的判定4个方面,对禁用偶氮染料检测的准确性进行探讨,提出提高纺织品禁用偶氮染料检测准确度的建议.
Abstract
Banning azo dyes will release carcinogenic aromatic amines which endanger human health.The detection of banned azo dyes in textiles is clearly required in in the national mandatory standards GB 18401-2010 and GB 31701-2015,and is also a key focus of export inspection.The detection accuracy of banned azo dyes in textiles is explored from four aspects:standard substances,recovery rate of pretreatment,separation of isomers,and determination of false positives.Suggestions are proposed to improve the accuracy of detecting banned azo dyes in textiles.
