In this paper,the experimental work on the determination of the molybdenum content in nickel alloys is reported in detail by the inductively coupled plasma atomic emission spectrometry of a mass dilution correction method.Through the sample dissolution test,the sample weighing test,the matrix interference test and the internal standard selection test,the analytical conditions were optimized,and the analytical method for the determination of molybdenum in nickel alloy by the inductively coupled plasma emission spectrometry was established.The method is accurate and reliable,which meets the requirements of the determination of molybdenum in nickel alloy.The method improves the ISO 11435:2011 standard by increasing the upper limit of determination of molybdenum from 20%to 30.00%,and has wider adaptability.The method is recommended as a national standard.
