摘要
采用硫酸亚铁铵容量法测定钒钛磁铁矿中钒,对选用两种分解样品方法所用的试剂,分解时间,温度,成本,滴定时的现象及准确度和精密度进行了对比,认定酸溶分解样品法优于碱熔分解样品法,其相对标准偏差(RSD)小于2.3%,方法简单快速且准确度较高。
Vanadium in vanadium titanium magnetite was determinated by ammonium ferrous sulfate volu- metric method . Two kinds of decomposition of sample methond were contrasted in time, temperature, cost, titration phenomenon , accuracy and precision. Acid decomposition of sample was better than alkali melt decomposition of sample, the relative standard deviation （RSD） was less than 2.3%, the method was simple rapid and high accuracy.
