| 摘 要： | 目的：建立测定商陆中砷和汞含量的方法。方法：采用湿法消解-原子荧光光谱测定商陆中总砷、总汞的含量。结果：砷在2～20ng/ml之间,汞在2～10ng/ml之间有良好的线性关系,砷：I=61.9200C-7.3370,r=0.9996;汞：I=576.8484C＋206.490;r=0.9971。总砷的平均回收率为98.8%,RSD为1.23%,检出限为0.0680ng/ml。总汞的平均回收率为101.85%,RSD为0.423%,检出限为0.135ng/ml。结论：本方法操作简便、测量准确,可作为中药商陆质量控制的方法。

| Abstract: | Objective：To establish a method for simultaneotts arsenic and mercury in Pokeiry Root. Method：The content of arsenic and mercttzy by Digested-Atomic Fluorescence Spectroscopy.Result：The linear range of As was 2-20ng/ml （r=0.9996）. The average recovely was 98.8% with RSD 1.23%.The linear range of Hg was 2-10ng/ml（l=0.9971 ）.The average recovery was 101.85% with RSD 0.423%.Under the optimizd conditions,the detectioI1 limit was 0.0680ng/ml and 0.135ng/ml for As and Hg,respectively. Conclusion： The naethods are stable and reliable which can be used in detemination of arsenic and nlercuty in PokebelaT Root. |
