摘　　要：研究电感耦合等离子体原子发射光谱(ICP-AES)法直接测定铁硅铝合金中的铈,选择最佳分析线,确定适宜的基体浓度,并研究了基体对铈测定的影响,得到铈的检出限为0.020μg/mL.用此方法对样品进行分析,得到分析结果的相对标准偏差RSD均小于2!(n=6),加标回收率为96!～106!.该方法简便、快速,准确,能够满足生产需要.A study was made of determining cerium in iron-silicon-aluminum alloy using inductance-coupled ICP-AES in the paper. The operation condition of the instrument was optimized, the composition of the alloy matrix determined, and its effect on the cerium determination studied, which yielded a detection limit for the cerium below 0. 020 μg/mL, a relative standard deviations RSD less than 2%（ n = 6）, and a recovery rate tested by standard addition method ranging from 96%to 106%. Being simple, rapid and precise, the method has been successfully applied to production practice.
