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.
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.
