Abstract:Chinese traditional herbal drugs for relieving away heat and toxic were treated with cineration,and the residues were dissolved by HNO_3.Eleven trace elements including,calcium,magnesium,manganese,copper,iron,zinc,cadmium,lead,cobalt,nickel and chromium in twenty sample solutions were determined by flame atomic absorption spectrometry.The results obtained show that the contents of calcium,magnesium,iron,zinc,manganese and copper are abundant,and the addition standard recoveries(n=5) were 90%-110%.
Keywords:Atomic absorption spectrometry  Chinese traditional herbal drugs for relieving heat and toxic material  Trace element
