| Abstract: | Objective To develop a method for determination of chromium in Sijiganmao Tablets by atomic absorption spectrophotometry, to provide basis for quality specification formulation. Methods The sample was detected by graphite furnace atomic absorption spectrometry after soaking in nitric acid overnight and microwave digestion. Results The linear correlation coefficient is 0.9981, and the average recovery is 96.9 %. The detection limit is 0.41 ng/ mL, and RSD of repeatability test is 1.6 %（n=6）. Conclusion This method can be used in quality control of Sijiganmao Tablets. Sijiganmao Tablets on the market are of low risk of chromium content. |
