| Abstract: | In this paper, the content of the eight inorganic element, K, Mg, Ca, Mn, Pb, Zn, Fe and Cu in cinnamon from Qin Ba Mountainous Area, were determined by closed microwave digestion and flame atomic absorption spectrophotometry （FAAS）. The results showed that the content sequence is K 〉 Mg 〉 Ca 〉 Mn 〉 Pb 〉 Zn 〉 Fe 〉 Cu. The recovery of the method is within 96.81% 115.6%. The method has the advantages of highly effective, simple, environment- friendly, reagents- saving and the digesting speedy. |
