Study on simultaneous determination of Bi and Hg in chinese herbal medicine by the sequential injection hydride generation atomic fluorescence spectrometry

XU Wen-jun(College of Chemistry and Chemical Engineering,Linyi Normal University,Linyi 276005)  
A method for the determination of Bi and Hg in chinese herbal medicine by sequential injection hydride generation atomic fluorescence spectrometry was established.The interference circumstance of the coexistence ions at the same time was discussed.Under the proposed conditions,the detection limits of the Bi and Hg were 0.0057 and 0.0197 μg/L.Recoveries of standard addition of the Bi and Hg have been proveed to be 93.4%~104.7% in samples.The maximum RSD was 4.3%.The coexistence ions in chinese herbal medicine samples hardly interfered in the determination of bismuth and mercury.The operation was easy and its sensitivity was high.This method is feasible and practicable to determine bismuth and mercury in chinese herbal medicine.
