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 + HNO3. Minor and trace elements were determined without matrix separation. The precision for all constituents was < 3%. Recoveries for the analyte-spiked samples were 95%. (C) 2002 Elsevier Science B.V. All rights reserved.
