摘要
激光诱导击穿光谱技术是一种具有吸引力的快速定量表征材料的方法,可用于工业过程的在线监控。本文报告了该技术在多元氧化物材料分析上应用。采用激光诱导击穿光谱技术分析钢工业生产的炉渣和混合氧化物试料,然后以无标定法测定其中氧化物的浓度,结果发现,对于本研究所涉及的材料,无标定激光诱导击穿光谱方法的测定浓度值与参考值一致,大部分样品和氧化物组分的绝对误差小于2%(质量分数),大范围改变测定参数时浓度值保持稳定。研究结果表明激光诱导击穿光谱技术作为钢铁工业中新型的分析测试技术具有很大潜力。
Laser-induced breakdown spectroscopy（LIBS） is an attractive method for fast and quantitative materials characterization that can be employed for in-line monitoring in industrial processes.We report on the application of LIBS to the analysis of multi-component oxide materials.Slag from industrial steel production and mixed oxide test materials are analyzed by LIBS and the concentration of oxides is determined by a calibration-free（CF） method.For all materials investigated we find good match of the calculated CF-LIBS concentration values with reference values.The absolute errors are less than 2 wt % for most of the samples and oxide constituents.The concentration values are stable against large variations of measurement parameters.Our results indicate that LIBS has significant potential for innovative analytical sensing in steel industry.
