摘要
目的:本文提出了用导数火焰原子吸收法测定中成药儿康宁中的微量铁、锌、钙的方法。方法:利用自制导数测量装置与火焰原子吸收分光光度计连接,对中成药儿康宁中的微量元素铁、锌、钙进行了测定。结果:检验出铁、锌、钙的含量分别为0.03939,0.0406,0.123mg·ml-1。结论:表明导数火焰原子吸收法具有较高的灵敏度、较低的检测限和较好的精密度。
Objective:To determine the contents of Fe, Zn, Ca in Erkangning, a kind of Chinese medicine, derivative flame atomic absorption spectrometry was used.Method:With derivative atomic absortion spectrometry.Results:The contents of Fe, Zn, Ca are 39.66 , 6.816 , 12.00 μg·ml -1 ,respectively.Conclusion:The derivative AAS is of higher sensitivity, lower detection limits and better accuracy.
