摘要:建立电感耦合等离子体原子发射光谱法测定钛合金中硼元素的分析方法。采用盐酸-氢氟酸-硝酸溶解钛合金样品,选择208.889 nm为硼的分析谱线,通过基体匹配法消除基体钛的干扰。在优化条件下对钛合金样品进行测定,线性相关系数大于0.999 0,硼的定量下限为0.000 5%,测定结果的相对标准偏差不大于3.00%(n=11),硼的加标回收率为95.00%~102.50%。该方法快速、准确,可以满足实际生产中钛合金样品的测定要求。
Abstract:Boron in titanium alloy samples was determined by inductively coupled plasma atomic emission spectrometry. The titanium alloy sample was dissolved with hydrochloric acid-sulfuric hydrofluoric-nitric acid dissolution. The analytical spectral lines of boron was 208.889 nm, the interference of titanium could be eliminated by matrix matching method. Under the selected conditions, the linear correlation coefficients were all more than 0.999 0, the detection limit of boron was 0.000 5%, the relative standard deviations of determination results were not more than 3.00% (n=11), and the recoveries ranged from 95.00% to 102.50%. This method can satisfy the determination requirement of niobium hafnium alloy samples in actual production for its celerity and accuracy.
