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试验;进行了对照试验、准确度和精密度等试验,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 study of the analysis methods for boron, silicon and aluminum contents in ferro-boron alloy, condition experiments were carried out for sample dissolution （melting）, working conditions, determination of apparatus conditions, selection of calibration curve and elimination of interference elements, while comparison, accuracy and precision experiments were also performed. This method uses alkali to melt and dissolve samples, adopts ferrite matrix added into standard solution as calibration curve and directly uses ICP-AES to determine boron, silicon and aluminum contents in ferro-boron alloy without adding internal standard elements. The method is simple, fast, accurate and practical, with the relative standard deviation at 0.50 % -5 %.
