摘要
通过对干扰元素和试剂加入量进行实验分析,建立了用硫酸铁铵滴定法测定铌钛铝基低密度铌合金中钛元素含量的方法,根据所用硫酸铁铵滴定溶液的体积计算样品中的钛含量。该方法钛元素含量加标回收率在98.48%~102.19%之间,RSD为0.37%。
The ammonium ferric sulfate mothod for the determination of titanium in the low density niobium alloy was established based on the experiment and analysis on the interference elements and the reagent contents.The titanium content in the sample was calculated according to the volume of titration solution.According to this method, the recovery rate of titanium was between 98.48% to 102.19% and the relative standard deviation was 0.37%.
