纺织品中砷和汞含量检测方法的研究进展

Analytical research on sources and contents of arsenic and mercury in textiles

为在检测纺织品中砷、汞含量时选出较优的检测方法,对比分析了分光光度计法、原子吸收光谱法、电感耦合联用技术、原子荧光分析法、X射线荧光光谱法、微波等离子体原子发射光谱法等方法。比较发现原子荧光分析方法对纺织品中的砷、汞的线性范围宽,稳定性好,成本低,适合推广。分析砷、汞测试方法未来发展方向,为相关方法改进提供参考。

In order to choosing optimum testing methods for As and Hg in textiles,the research on testing methods of As and Hg recently,including spectrophotometer,atomic absorption spectrometry,inductively coupled technology,atomic fluorescence analysis,X ray fluorescence spectrometry,microwave plasma atomic emission spectrometer,etc.were compared and analyzed.The results show that atomic fluorescence spectrometry method had some advantages,such as wide linear range,good stability,low cost and easy popularization,the research providing references for further improvement of testing methods for As and Hg.
