ABSTRACT
Methods for determination of heavy metals and harmful residues in traditional Chinese medicine injection were established. Graphite furnace atomic absorption spectrometry was used for determination of lead, cadmium and copper, atomic fluorescence spectrometry for arsenic and mercury. The preprocessing method was optimized. The average recoveries of 5 elements were between 91% and 112% while the precisions were less than 2%. The determination limit of lead, cadmium, copper, arsenic and mercury were 0.28, 0.014, 0.49, 0.19, 0.061 microg x L(-1), respectively. The proposed method was simple, sensitive, accurate and reliable, and could be used widely.
