Chinese traditional herbal drugs for relieving away heat and toxic were treated with cineration, and the residues were dissolved by HNO3. 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%.
将清热解毒品类的中药进行灰化处理，残渣用硝酸溶解。采用火焰原子吸收光谱法测定20份样品溶液中的钙、镁、锰、铜、铁、锌、镉、铅、钴、镍和铬等11种微量元素。结果表明，钙、镁、铁、锌、锰和铜的含量丰富，加标回收率（n = 5）为90% - 110%。
