氢化物发生原子荧光光谱法同时测定进出口玻璃食具、器皿中有害元素砷、锑迁移量

Simultaneous determination of harmful elements arsenic and antimony migration from glass food container and ware for import and export

建立氢化物发生原子荧光光谱法(HG-AFS)同时测定进出口玻璃食具、器皿中砷、锑迁移量的方法,并对HG-AFS工作参数及条件进行优化和选择。As检出限为0.02μg/L,Sb检出限为0.03μg/L;回收率范围为96%～101%。本法操作简便、快速、灵敏度高,应用于进出口玻璃食具、器皿中砷、锑迁移量的检测取得了满意的结果。

A method for the simultaneous determination of harmful elements arsenic and antimony migration from glass food container and ware for import and export by HG-AFS method has been developed. Operation parameters of HG-AFS and condition were optimized and selected. The detection limit was As 0.02 μg/L, Sb 0.03 μg/L. The recovery was in the range of 96%-101%. This method has the feature of easy operation, fast speed and sensitivity and it has been applied to the determination of arsenic and antimony migration from glass food container and ware for import and export with satisfactory results.
