ICP-AES法测定钛合金中的6种元素

Determination of Six Elements in Titanium Alloys by ICP AES

用 HCl分解钛合金样品 ,直接用 ICP- AES法测定其中的 Cr、Mo、Fe、Si、Al及 Zr6种元素 ,方法简便、快速。测定各元素含量范围为 0 .2 8%— 6.51% ,相对标准偏差为 0 .72 %— 5.0 7% ,回收率为 97.4 %—10 2 %

Cr,Mo,Fe,Si,Al and Zr in titanium alloys were determined by ICP AES,the sample of titanium alloys was decomposed with HCl(1+1).This method efficient and rapid,the content range of every element is of 0.28%-6.51%, the RSD is 0.72%-5.07% and the recoveries are 97.4%-102%.
