摘　　要：采用电热原子吸收光谱法测定了钢铁样品中的痕量钙,加标回收率为95.0%—110.0%,相对标准偏差在4.6%—6.4%之间,本法适用于那些不具备昂贵价格大型仪器的实验室,更适用于生产流程控制检测。The trace calcium in steel samples were determined by electrothermal atomic absorption spectrometry,and recoveries were in the range of 95.0%—110.0%with RSDs from 4.6%to 6.4%.The method is appropriate for those laboratories who do not have expensive instruments,especially for control detection in production process.
