Abstract：The co linear determination of boron in pig iron, cast iron, stainless steel and low medium alloy steel materials was realized using direct current glow discharge emission spectrometer. The sample was prepared using grinding machine. The excitation parameters were optimized with single factor alternation method. The matrix effect of different materials was eliminated using iron as matrix element. The spectral interference of molybdenum was corrected. The optimized analytical parameters were as follows: discharge voltage, 1 200 V; discharge current, 50 mA; pre sputtering time, 50 s; integration time,10 s; correction coefficient for spectral interference of molybdenum,-0.007 9. The analytical range of boron was 0.000 6 ％ 0.080 ％. The determination results were consistent with the certified values. The relative standard deviation (RSD) was smaller than 3 %.
