嘎日迪-13和嘎日迪-15中14种元素含量的比较研究

摘要

采用ICP-AES法同时测定嘎日迪-13和嘎日迪-15中的Si、Sn、Al、Cd、Na、P、K、Ca、Mn、Fe、Cu、Zn、Mg和Pb等14种元素含量，并对各元素进行了加标回收实验,嘎日迪-13和嘎日迪-15中各元素的回收率在92.78%～105.56%之间，RSD在0.87%～3.93%之间.结果显示，在嘎日迪-13和嘎日迪-15中K、P、Ca、Na、Fe、Mg等元素含量较高，Pb未检出.%Determine the Si, Sn, Al, Cd, Na, P, K, Ca, Mn, Fe, Cu, Zn, Mg and Pb and other 14 kinds of element content from Garidi-13 and Garidi-15 by ICP-AES method. And the elements were spiked. The average recoveries of ele-ments from the Garidi-13 and Garidi-15 are between92.78%~105.56%, and the RSD is between 0.87%to 3.93%. The results show that the K ,P, Ca, Na, Fe, Mg and other content of elements in Garidi-13 and Garidi-15 were high, and Pb was not detected .
