摘要
本文对茜素中微量元素钾、钠、钙的火焰原子吸收法的测定进行了研究,结果表明:方法简单,具有很好的精密度和准确度。钾、钠、钙的相对标准偏差分别为:4.4%、2.5%和3.7%。回收率分别为97.5%,98.3%和98.1%。
This paper reports the development of the determination of trace metals K,Na and Ca in alizarin.The method is convenient to determine elements in alizarin by flame atom absorption spectrophotometry.The results show that the method has good precision and accuracy.The relative standard deviations of K,Na and Ca are 4 4%,2 5% and 3 7%,respectively,and the rates of recovery are 97 5%,98 3% and 98 1% respectively.
