| 摘 要： | 目的：建立火焰原子吸收分光光度法测定藏药中铁含量的检测方法,以控制藏药质量。方法：采用稀硝酸消解法处理样品,采用火焰原子吸收分光光度法测定样品中Fe2＋含量,并优化相关实验参数。结果：Fe2＋浓度（C）在1.09~16.31μg/mL范围内与其吸光度（A）呈良好的线性关系,相关系数r=0.999;回收率为97.15%,RSD%=0.74（n=6）。结论：火焰原子吸收法能安全、快速、高效地测定藏药复方制剂中的铁含量,可用于藏药及其制剂的质量控制。

| Abstract: | Objective： Establishment of detection method for determination of iron content in Tibetan medicine by flame atomic ab- sorption spectrophotometry, for the purpose of control quality of Tibetan Medicine. Methods： By using the method of dilute nitric acid digestion to replace the existing mixed acid digestion, flame atomic absorption spectrophotometric determination of the content of Fe2＋ instead of titration. Results ： Fe2＋ absorbance （A） and concentration （C） of 1.09μg/mL～ 16.31μg/mL range, the correlation coefficient r=0. 999; the rate of recovery was 97.15, RSD%=0.74（n= 6）. Conclusion：The method can safe, quick, efficient de termine the content of iron of Tibetan medicine. |
