摘要
目的建立原子荧光光谱法同时测定人参中砷和汞的含量。方法采用微波消解法对样品进行消解,优化确定实验条件,应用双道原子荧光光度计,对样品进行测定。结果此方法样品处理简单快速,实验线性范围高(大于三个数量级),检出限低(砷AS:0.02ug/L,汞Hg:0.002ug/L),重现性强,简化了实验步骤,对于批量检测任务,大大提高了工作效率,具有极高的推广价值。
Objective to establish that the determination of arsenic and mercury content in ginseng at the same time by atomic fluorescence spectrometry. Method： The samples by microwave digestion using nitric acid to dissolve,the optimum of experiment conditions were determined, by dual channel atomic fluorescence photometer, the determination of the samples. Rssult： This approach is simple and rapid for processing samples. the linear range is higher（more than three orders of magnitude）, detection limit is lower（arsenic AS： 0.02 ug/L, mercury Hg： 0.002 ug/L）.Conclusion： This method reproducibility is stronger. It simplifies the experimental steps,improving the work efficiency greatly, for batch testing tasks, with higher popularization value.
