摘　　要：本文建立了用电感耦合等离子体发射光谱法(ICP-AES)测定铝钛-硼合金中钛、硼、铁、硅、钾、锌、锰、镁、镍、钒10种元素含量的分析方法。测定时分别选择Ti 336.121nm(Ⅱ)、B 249.772nm(Ⅰ)、Fe239.562nm(Ⅱ)、Si 251.611nm(Ⅰ)、K 766.490nm(Ⅰ)、Zn 206.200nm(Ⅱ)、Mn 257.610nm(Ⅱ)、Mg 285.213nm(Ⅰ)、Ni 231.604nm(Ⅱ)和V 290.880nm(Ⅱ)作为各元素的分析线。确定了仪器的最佳分析条件:射频功率1350W,雾化器流速0.8L/min,观测高度为14.0mm。采用基体匹配法消除基体干扰,经实验.本方法的回收率在90%～105%之间,测定结果的相对标准偏差(n=6)在0.4%～4.3%之间。该方法准确、快速,具有良好的精密度和准确度,能够满足日常生产检测需要。The amounts of ten elements （Ti, B, Fe, Si, K, Zn, Mn, Mg, Ni and V）in Al-Ti-B alloys were determined simultaneously by ICP AES. The analytical lines, which were chosen to characterize the ten elements included Ti 336. 121nm（Ⅱ）, B 249. 772nm（Ⅰ）, Fe 239. 562nm（Ⅱ）,Si 251. 611nm（Ⅰ）, K 766. 490nm（Ⅰ）, Zn 206. 200nm（Ⅱ）,Mn 257. 610nm（Ⅱ）,Mg 285. 213nm（Ⅰ）,Ni 231. 604nm（Ⅱ0Dand V 290. 880nm（Ⅱ）. The optimal instrument conditions were determined as following= 1350W of frequency power, 0.80L/min of nebulizer gas flow and 14.0mm of view distance. The matrix induced interference was eliminated by matrix matching method. Precision and recovery were tested, giving results of recovery in the ranges of 90%-105% with RSD （n=6） of 0.4%-4.3%. It concluded that the method was accurate and simple with satisfactoryprecision and was suitable for routine quality control analysis.
