To test lead content for traditional Chinese medicine areca slice, the experiment choose convenient ion flotation method to separate higher enrichment and sensitivity flame atomic absorption spectrophotometry to test content of trace lead in the sample. According to the analysis of tested data, the effectiveness of the proposed method for concentration of lead were discussed, which was found that the adopted floatation separation of Lead with ammonium sulfate-potassium iodide-cetylpyridine bromide system floating method had better feasibility for the separation and enrichment of lead. At the same time, the method had higher practicability and accuracy to provide reliable and convenient way for lead content of test material in the future.
