Abstract：The determination of Si and B content in Fe-based amorphous alloy steel by spark source atomic emission spectrometry was studied. The stability of analytical line strength of Si and B in amorphous alloy steel was tested and compared. Si 212.41 nm and B 345.14 nm were selected as analytical lines. The optimal pre-ignition time for Si and B analysis was 13 s. The calibration curves of Si and B were prepared using some international standard samples and self-developed internal control samples. Then, the curve fitting was conducted after deducting the elemental interference. The calibration curve of high content Si (mass fraction of 3.15%-7.04%) was prepared using analytical line Si 212.41 nm, and the curve range in original software was broadened to 0.003%-7.04%. The calibration curve of high content B (mass fraction of 0.90%-3.31%) was prepared using analytical line B 345.14 nm, and the curve range of B was broadened to 0.000 1%-3.31%. The content of Si and B in amorphous alloy sample was determined according to the experimental method. The relative standard deviations (RSD, n=10) were less than 1.0%. The accuracy test results indicated that the determination results of proposed method were consistent with those obtained by inductively coupled plasma atomic emission spectrometry (ICP-AES).
