摘要
目的测定市场上四季感冒片铬含量,为制定四季感冒片标准提供参考数据。方法采用硝酸浸泡过夜,微波消解,石墨炉原子吸收光谱法测定。结果线性相关系数为0.9981,加样回收率96.9%,检出限0.41 ng/mL,重复性RSD为1.6%(n=6)。结论此法可用于四季感冒片质量控制,结果表明,市场上四季感冒片铬含量潜在风险较低。
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.
