Abstract

A method is developed for determining Ca, Mg, Zr, Hf, V, La, Ce, and Y in heat-resistant nickel alloys (HNAs) by inductively coupled plasma atomic emission spectrometry. A scheme of the dissolution of tests of HNA samples of different brands in a microwave digestion system is proposed. Analytical lines of elements and of the internal standard, free from significant spectral suporpositions, are chosen. The effect of the time of accumulation of the analytical signal on the limits of quantification of elements is studied. Performance characteristics of the procedure are estimated in an analysis of model solutions and the accuracy of the results is estimated using standard samples of nickel alloys.

摘要

开发了一种通过电感耦合等离子体原子发射光谱法测定耐热镍合金（HNA）中Ca，Mg，Zr，Hf，V，La，Ce和Y的方法。提出了在微波消解系统中溶解不同品牌的HNA样品的测试方案。选择没有明显光谱重叠的元素和内标物的分析线。研究了分析信号积累时间对元素定量限的影响。该过程的性能特征在模型解决方案的分析中进行了评估，结果的准确性通过使用镍合金的标准样品进行了评估。
