| Abstract: | The contents of Pb and Cd were determined by graphite furnace atomic absorption spectrometry (GF-AAS). The microwave- assisted sample digestion method and determination method for Pb and Cd in the Mollugo pentaphylla L. were established. The results indicated that the contents of Pb and Cd were 3.027 μg·kg~(-1)(recovery 97.25%) and 1.021 μg·kg~(-1)(recovery 100.03%)respectively. The graphaite furnace atomic absorption spectrometric determination method is simple, high-speed, sensitive and accurate, which can be used to determine Pb and Cd in other traditional Chinese medicine. |
