Analysis of nickel-niobium alloys by inductively coupled plasma optiocal emission spectrometry

摘要

Inductively coupled plasma optical emission spectrometry (ICP-OES) was applied to the analysis of major and minor elements of Ni-Nb alloys obtained by aluminothermic reduction process. Digestion of samples was made using a mixture of HF-HNO_3. Minor and trace elements were deterined without matrix separation. The precision for all constituents was < 3%. Recoveries for the analyte-spiked samples were 95%.
