摘要探究了钛铌合金的溶解及使用电感耦合等离子体原子发射光谱(ICP-AES)测定该合金中高含量铌的方法。实验采用硫酸和氢氟酸溶解钛铌合金,在优化的操作条件下,采用基体匹配法和内标法相结合的方法消除干扰。选择波长Nb 269.7 nm谱线为分析线,钒作为内标元素、268.7 nm波长的谱线作为内标线。方法的线性范围为0.5%～95%,线性相关系数r=0.999 7。用于Ti-45Nb合金中铌的测定,相对标准偏差(n=6)为0.46%,加标回收率在99%～102%之间。方法快速、准确, 可用于钛铌合金中高含量铌的测定。

Abstract：A study was conducted on the dissolution of titanium-niobium alloy and determining high content of niobium by inductively coupled plasma atomic emission spectrometry(ICP-AES). By dissolving titanium-niobium alloy with sulfuric acid and hydrofluoric acid and under optimum operation condition, matrix matching method and internal standard method were used to eliminate the interference. Nb 269.7 nm spectral line was selected as analysis line while V 268.7 nm spectral line was selected as internal standard line. The linearity of the method was 0.5%-95% while the linear correlation coefficient was 0.999 7. The proposed method was applied to determine niobium in Ti-45Nb alloy with the RSD (n=6) of 0.46% and the recovery of 98%-102%. Due to its fast and accurate determination, this method could be used for determining high content of niobium in titanium-niobium alloy.
