| 摘 要： | 采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W，Nb，Ta元素的含量。样品采用盐酸、氢氟酸和硝酸溶解，并对仪器工作参数和试验条件进行了优化试验，确定了仪器最佳工作条件，考察了钛合金基体和共存元素对待测元素的影响，确定了各待测元素谱线为W207．911nm，Nb309．418nm，Ta240．063nm。选定的待测元素分析线不受合金基体和共存元素的干扰，通过基体匹配消除基体的影响。加标回收率在98％104％之间，测定结果的相对标准偏差为0．3％～2．4％（n=8），方法的检出限为0．003-0．013μg／mL。进行了标准物质对照试验，试验结果与标准值相符。

| Abstract: | The content of tungsten, niobium, tantalum in titanium alloy was determined simultaneously by inductively coupled plasma atomic emission spectrometry（ICP-AES）. The sample was decomposed with HC1, HNO3 and HF. The interference from matrix and co-existing elements were studied. The analysis lines of tungsten, niobium, tantalum were 207.911,309.418,240.063 nm, respectively. The matrix effect was corrected by matrix matching. The detection limit was 0.003-0.013μ g/mL, the recovery rate was from 98% to 104%, the relative standard deviation of determination results was 0.3%-2.4%（n=8）. The determination results were in good agreement with reference materials. |
