ABSTRACT
Objective To develop a method to determine Pb and Cd in Qingkailing Injection by graphite furnace atomic absorption spectrometry, and search their source. Methods The samples, digested via microwave, were determined the contents of Pb and Cd by graphite furnace atomic absorption spectrometry in raw material, intermediate and finished product of Qingkailing Injection. Results The standard curve of Pb was Y=0.007 3X+0.011 6, and Cd was Y=0.056 7X+0.060 4. The regression equation of Pb and Cd was 97.0% and 95.6%, respectively. Content determination of Pb and Cd in Qingkailing Injection revealed that Pb and Cd in finished product came from raw materials. Conclusion The method is rapid, high sensitive and accurate, and can be applied to the inspection of Pb and Cd in Qingkailing Injection.
