Atomic Absorption Spectrometry to Measure the Content of Titanium in the Stainless Steel

  • 摘要: 采用了N2O-C2H2火焰原子吸收光谱法测定不锈钢材料中钛.介绍钛的最佳测定条件以及线性范围的浓度.在样品测定中对干扰因素进行了综合考虑.实验表明:该方法灵敏度高、干扰小、选择性好、操作简便、容易掌握、分析周期短等优点.测定样品钛1.0~60.0mg/L时,其相对标准偏差均小于1.0%(n=6).标准加入回收率均为97.0%~100.0%(n=6)之间.该方法用于不锈钢材料中钛的测定,结果满意.

     

    Abstract: The nitrous oxide-ethane flame atomic absorbing spectral method to measure the content of Titanium in stainless steel is studied.This paper introduces the optimum measuring conditions for Titanium and the potency in which a fine liner range, and makes also a synthetic consideration to interference factors. The method has the advantages of high sensitivity, less interference and good in selectivity and reappearance. The relative standard deviations are all less than 1.0%(n=6)in six sample measuring, and the standard adding recovery is in the range of 97.0%~100.0%(n=6). The practice shows that the method is fully suitable to measuring the content of Titanium in the stainless steel.
