几种新型样品前处理技术在禁用偶氮染料检测中的可行性分析

Feasibility Analysis of Several New Sample Preparation Techniques in the Detection of Banned Azo Dyes

禁用偶氮染料的监控已成为国际纺织品服装贸易中最重要的品质控制项目之一,也是生态纺织品最基本的质量指标之一。本文概述了几种新型样品前处理技术,并对其在禁用偶氮染料检测的应用进行了可行性分析,进而提出将分散液液微萃取作为纺织品中禁用偶氮染料检测的新型前处理技术。

The monitoring of barmed azo dyes has become one of the most important quality control projects in the international trade of textiles and clothing. It is also one of the basic quality indicators of ecological textiles. In this paper, the theory and characteristics of several new sample preparation techniques were introduced. Then the feasibility of these new sample preparation techniques in the detection of banned azo dyes was analyzed. Furthermore, dispersive liquid liquid microexlraction （DLLME） was proposed as the sample preparation technique in the detection of banned azo dyes in textiles.
