介绍了用电感耦合等离子体原子发射光谱法（ICP －AES）法测定钛合金中Mo、Nb、Al、Fe、Si元素的方法。样品采用盐酸、氢氟酸和硝酸溶解，考察了钛合金基体和共存元素对待测元素的影响，确定了各待测元素分析线分别为Mo 202·031 nm 、Nb 269·706 nm、Al 394·401 nm、Fe 239·562 nm、Si 251·611 nm。选定的待测元素分析线不受合金基体和共存元素的干扰，通过在校准曲线溶液中进行基体匹配消除基体的影响，通过加入内标控制测量波动，选择了仪器工作参数，进行了标准物质对照试验，试验结果与标准值相符，进行了加入回收试验，回收率在90～110％之间，相对标准偏差小于6％。

A method for determination of Mo ,Nb ,Al ,Fe and Si in titanium alloy by ICP‐AES was studied. The sample was decomposed with HCl ,HF and HNO3. The analysis lines were Mo 202.031 nm , Nb269.706 nm ,Al394.401 nm ,Fe239.562 nm and Si251.611 nm ,respectively ,the effect of matrix and co‐exist elements on the determination were investigated ,the instrument parameters were carried out. The determination results were in good agreement with standard reference material ,the recovery rate was from 90 to 110% ,the RSD was less than 6%.
