| Abstract: | OBJECTIVE： To analyze the uncertainty in the determination of plumbum in Glycyrrhiza uralensis by graphite furnace atomic absorption spectrometry. METHODS： Graphite furnace atomic absorption spectrometry was used to determine the content of plumbum in G. uralensis and the uncertainty of the determination was estimated according Evaluation and Expression of Uncertainty in Measurement. RESULTS： The expanded uncertainty was obtained （k=2, confidence probability of 95 % ）. CONCLUSION： The study provides reference for analysis of uncertainty in the content determination of heavy metal and harmful elements in traditional Chinese medicines by atomic absorption spectrometry. |
