Determination of the Content of Iron, Titanium and Zirconium in Refractory Materials by Using ICP-AES

摘要

Determination of the content of iron, titanium and zirconium in refractory materials by using ICP-AES method, which is melt by high temperature and dissolved by acid was discussed in this paper.Using mixed standard solution scans the single elements peak, select suitable analytical spectral lines and optimize the instrument conditions.The results showed that the sample can be melt at high temperature of 1050 ℃.The standard addition recovery is between 97％ and 104％ and the linear coefficients of standard curve are more than 0.999.This method is suitable for rapid analysis and measurement of the elements in refractory materials.
