| Abstract: | Objective：To establish a graphite furnace atom absorbance spectrometry （AAS） method for determination of Pb content in Shuanghuanglian injections. Methods： Appling microwave digestion system to deteriorate sample. Use graphite furnace AAS method to determine Pb content. Results： The linear relationship between the absorbance and the concentration of Pb was in the range of 0-80μg·L^-1 （r=0.9989） with detection limit of μg·L^-. Conclusion： This method is found to be sensitive and accurate and was useful in control the content of Pb in Shuanghuanglian injections. |
