This article was about using a rapid and accurate method to determine four elements(W,Mo,Cr,Zr)from GH3128.The samples were dissolved by hydrochloric acid and nitric acid under the low temperature heating condition.The content of these four elements in the solution was determined by inductively coupled plasma atomic emission spectrometry(ICP-AES).The analytical spectral lines were W207.912 nm,Mo202.031 nm,Cr284.325 nm and Zr343.823nm,and the appropriate working parameters of the spectrometer were selected.The matrix matching method was used to eliminate the influence of matrix components to generate the working curve.The detection limits(3s)of each element were 6.3,5.6,2.5,1.9 μg·mL-1,and the relative standard deviation(n=10)was 1.1%-3.1%.The GH3128 reference material was analyzed by the above method,and the measured value was consistent with the confirmed value.
