ICP-AES法测定DD2单晶合金中的铼和铪

Determination of Re and Hf in DD2 Single Crystal Alloys by ICP AES

本文采用ＩＣＰ－ＡＥＳ法对ＤＤ２单晶合金中铼、铪的测定进行了研究，着重考察了ＤＤ２合金中基体及共存元素对铼，铪测定的影响。采用基体匹配法消除基体干扰，测定了ＤＤ２合金中的铼，铪含量，得到了较好的精密度和准确度。方法简便快速，可获得满意的分析结果。

The determination of Re and Hf in DD2 single crystal alloys by ICP AES is studied in this paper. The effects of metrix and co exist elements in DD2 alloys on contents of Re and Hf is emphatically studied. The metrix matching method is used to eliminate metrix interference and to determine the conterts of Re and Hf in DD2 alloys, high precision and accuracy is achieved.
