Abstract：The corrosion resistance of nickel-based alloy is excellent,but it is difficult to be dissolved.The nickel-based alloy sample was decomposed with hydrochloric acid-nitric acid-hydrofluoric acid by microwave digestion.Si 288.158nm,Cr 267.716 nm and B 249.678 nm were selected as the analytical lines.The matrix matching method was used to eliminate the influence of matrix effect and the automatic matching method (FITTED) was used to correct the spectral line interference.By diluting the solution,the detection range of chromium element was expanded.Consequently,the determination method of silicon,chromium and boron in nickel-based alloy by microwave digestion-inductively coupled plasma atomic emission spectrometry (ICP-AES) was established.When the mass fraction of silicon,chromium and boron was 0.1%-2.0% (mass fraction,similarly hereinafter),0.1%-2.0% and 0.01%-0.1%,the emission intensity was linear to the corresponding mass fraction.The linear correlation coefficients of calibration curves were not less than 0.999 4,and the limits of detection were not more than 0.000 2%.The contents of silicon,chromium and boron in nickel-based alloy were determined according to the experimental method.The relative standard deviations (RSD,n=6) of determination results were between 0.70% and 1.8%.The proposed method was applied for the determination of certified reference materials of nickel-based alloy,and the found results were consistent with the certified values.
