In this paper, by examining the impact of various factors on the digestion effect of the sample and optimizing the conditions of graphite furnace atomic absorption, a rapid and effective method for the determination of cadmium in traditional Chinese medicine was established. The detection limits were 0 0 1 1 9 ng · mL- 1, the linear range is 0 0 6 ~ 2 ng · mL -1, the recovery of the sample is 91 7% ~ 1 0 4 3%, the result is satisfactory
