摘　　要：对于制备镍氢电池负极材料的 AB5型储氢合金 ,制备储氢合金的原材料混合稀土主体元素和杂质元素的分析方法进行了较为详尽的研究。利用仪器的功能软件初步选出各分析元素的多条谱线 ,通过综合考察各干扰元素对分析元素波长的干扰系数 ,确定出各元素的最佳分析波长 ,部分受干扰的元素用干扰系数校正法进行了校正。本法应用于实际产品分析 ,分析精密度为 0 .12 %— 1.32 %之间 ,回收率在94 %— 10 6%之间。The analytical method of major elements and trace elements in AB_5 type hydrogen storage alloys and mischmetal was researched deeply.With the functional software of instrument,the analytical lines of each element were initially selected.The optimum analytical line of each element was confirmed by overall investigation of the interference coefficients.Some of elements being interfered were corrected by interference coefficient correction method.The method has been applied on the analysis of realistic products and the results show that the relative standard deviation is in the range of 0.12%—1.32% and the recovery rate is in the range of 94%—106%.
