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