Abstract:
Objective To establish the method of determining the content of lead in Cynomorium Songaricum Rupr.by atomic fluorescen spectrometry.Method After digested by perchloric acid-nitric acid,atomic fluorescen spectrometry was used to determining the content of lead in Cynomorium Songaricum Rupr..Results When the concentration of trace lead was 0.00～10.00 ng/mL,it had linear relationship with fluorescence intensity.The linear function was Y =408.459 3X-72.159 5,and the linear correlation coefficient was 0.999 5.The relative standard deviation of six determination results of the samples was 2.8%.The recovery rate was 93.7%～96.0%.Conclusion The method is featured by easy operation,fast speed and good sensitivity.
