电感耦合等离子体原子发射光谱法测定镍合金中的铬含量
Determination of Chromium Content in Nickel Alloy by Inductively Coupled Plasma Atomic Emission Spectroscopy
摘要
Abstract
The method for determination of chromium in nickel alloy in international standard ISO 7530-1:2015 using a nitrous oxide-acetylene flame atomic absorption spectrometry has been rarely used.In this paper,the experimental work on the determination of chromium by inductively coupled plasma atomic emission spectrometry is reported.Through sample dissolution test,sample weighing test,matrix interference test and internal standard selection test,the analytical conditions were optimized,and the analytical method for the determination of chromium in nickel alloy by inductively coupled plasma emission spectrometry was established.The method is accurate and reliable,which meets the requirements of the determination of chromium in nickel alloy.The method is recommended as a national standard.关键词
