摘　　要：通过对硼铁合金中硼、硅和铝含量分析方法的研究，开展了试样溶解（熔融）条件的选择、仪器工作条件的确定、校准曲线的选择和干扰元素的消除等条件实验；进行了对照实验、准确度和精密度等实验，本法采用碱熔融分解试样，选用铁基体加入标准溶液为校准曲线，在不需要加入内标元素的条件下，可以直接应用电感耦合等离子体原子发射光谱分析技术测定硼铁合金中硼、硅和铝的含量；本法试剂加入少，操作简便，可实用于生产检验，相对标准偏差为0．5％-5．0％。Through the research and analysis methods of boron, silicon and aluminum content of i-ron alloy, the experiment is carried about the sample dissolution （ melting） , working conditions , de-termination of instrument’ s conditions, the choice of calibration curve and the elimination of interfer-ence elements. The experiment is developed by comparison , accuracy and precision.This method a-dopts the high temperature melting the sample decomposition,simultaneously the iron is added in solu-tion. Without the addition of internal standard elements, this method can determinate Ferroboron ’ s boron, silicon and aluminum sample by ICP-AES directly.This method is simple , rapid and accu-rate.The relative standard deviation was 0.5%-5.0%.
