中文摘要:
      建立了采用电感耦合等离子体原子发射光谱(ICP-AES)法测定钒铝、铬铝中间合金中铁、硅含量的分析方法。通过对溶样酸选择、基体干扰、加标回收和精密度等实验条件的考察,确定了方法测定范围为0.010%~0.50%。解决了以往分光光度法测定时操作复杂、费时费力的问题,为大规模生产的质量控制提供了有效的技术,对以后相似合金铁、硅含量的测定提供参考。
英文摘要:
      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.
