| Abstract: |
| Trace impurities of iron (Fe) and silicon (Si) are an important quality indicator of vanadium-aluminum and chromium-aluminum alloys. In this paper, an inductively coupled plasma-atomic emission spectrometry (ICP-AES) method has been developed for the determination of Fe and Si content in vanadium-aluminum and chromium-aluminum master alloys. By selection of optimum conditions, precision in the range of 0.010 % – 0.50 % has been achieved. The presented method is simpler and faster than the conventional spectrophotometric method which is complex and time-consuming, providing effective technical support for the quality control during mass production of vanadium-aluminum and chromium-aluminum alloys. |
