中文摘要: 通过对辉光放电发射光谱参数的优化，以铁元素为内标来消除基体效应，建立了测定硅钢薄板中微量硼元素的方法。优化的实验参数为放电电压1200 V，放电电流50 mA，预溅射时间40 s，积分时间10 s。校准曲线硼元素含量范围0.0001％~0.022％，相关系数大于0.999，测量结果与认定值一致，相对标准偏差小于10%。完全能够满足日常分析测试的要求。
Abstract:A glow discharge optical emission spectrometry (GD-OES)
method for determining trace boron element in silicon steel sheets were established through optimization of instrumental parameters and using Fe element as an internal standard to eliminate the matrix effect. The optimized instrumental parameters included discharge voltage, discharge current, pre-sputtering time and integration time, which are 1200 V, 50 mA, 40 s, and 10 s, respectively. The content of boron element that can be determined from the calibration curve ranges from 0.0001% to 0.022% and the linear correlation coefficient is more than 0.999. The testing results are consistent with the certified values and the relative standard deviations are below 10%.
