纺织品中残留汞的高灵敏度测定方法

High Sensitive Determination of Residual Mercury on Textiles

对应用循环富集装置,配以冷原子吸收测汞系统,测定纺织品中的残留汞含量进行了介绍。试样经人工汗液、唾液浸取后,循环装置富,冷原子吸收法测定。本方法简便、快速、灵敏,检出限0.020μg/mL,添加回收率为90.1％～97.0％,变异系数4.30～8.51％。

Rely on enriched circulating device combined with cold-atom absorbed mercury testing system, the content determination of mercury remains in textiles is introduced. After soaking with perspiration and saliva, the sample is enriched by circulating device and tested with cold-atom absorbed method. The testing method features simple, rapid, sensitive, as well as limit content 0.02μg/mL, added recovery ratio 90.1～97.0%, variation index 4. 30～8.51%.
