Determination of Rare-Earth Metal and Ca, Mg, V, Zr, and Hf Microadditives in Nickel Alloys by Atomic Emission Spectrometry

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 li...

Description
Summary: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.
