Abstract:  A microwave-digestion procedure was developed for the determination of trace Cu, Zn, Mn and Ni in Acorus calamus L by flame atomic absorption spectrophotometer. The result shows that it contains four essencial elements such as Cu, Zn, Mn and Ni. The experimental results showed that the detection limits is all smaller than 0.046μg/ml, the RSD (n=8) is all smaller than 2.90%, and the addition standard recovery(ASR)(n=8) is 99.13%~107.0% for all elements.

Key words: microwave-digestion, atomic absorption, trace element
