Objective To establish the analysis method for determination of the 5 kinds of heavy metals (Pb、Cd、As、Hg、Cu) in Zhuang-drug Meiqiaobei. Method The samples were digested by mix acid using the Microwave and determined of the 5 kinds of heavy metals (Pb、Cd、As、Hg、Cu) in Zhuang-drug Meiqiaobei by indu ctively coupled plasma mass spectrometry (ICP-MS). Result Detection limits for above elements were 0.0048~0.0518ng/mL,with the recoveries were 87%~97%,The results obtained showed close agreement with the national standard substances of tea leaves (GBW10016). Conclusion This method is fast , accurate and reliable,which can be used to determinate the contents of the 5 kinds of heavy metals (Pb、Cd、As、Hg、Cu )in Zhuang-drug Meiqiaobei.
