Determination of Trace Pb and Cd in Corydalis yanhusuo by Microwave Pressure Acid Digestion-Atomic Absorption Spectrometry

FENG Zi-li(Shaanxi Provincial Key Laboratory of Bio-resource,Shaanxi University of Technology,Hanzhong,Shaanxi 723001)  
[Objective] The study aimed to determine the heavy metal elements in Corydalis yanhusuo by microwave pressure acid digestion-graphite furnace atomic absorption spectrometry.[Method] With C.yanhusuo from Hanzhong City of Shaanxi Province as sample,and the sample was digested by mixed-acid,the trace Pb and Cd in C.yanhusuo medicinal materials were determined directly by adopting microwave pressure acid digestion-graphite furnace atomic absorption spectrometry,and the reagent and conditions of microwave digestion were also screened and optimized.[Result] The result was the best with HNO3+HClO4 as digestive reagent.Under optimized experiment conditions,the average content of Pb and Cd detected were 0.947 and 0.074 μg/ml resp.the relative standard deviation(RSD) of content determination were 0.41% and 1.32% resp.,the recoveries of standard addition were 92.2% and 89.8% resp.The analysis results showed that the trace Pb and Cd content in C.yanhusuo sample from Hanzhong City of Shaanxi Province conformed to national standard.[Conclusion] Determining the trace elements in Chinese medicinal materials by microwave pressure acid digestion-graphite furnace atomic absorption spectrometry,the easy,rapid,accurate and sensitive results could be achieved.
