摘    要：采用碘量法测定铌铁、钽铁精矿中锡量对滴定的酸度，碘酸钾与碘化钾的比例，还原剂的选择进行了实验，选取了最佳的滴定条件并进行了干扰元素的实验，采取了较简便的方法分离了干扰元素。

Abstract:

This paper studied the titration acidity, the ratio of potassium iodate and potassium iodide, the choice of reducing agent to select the optimal titration conditions. Experiments on interfering elements were conducted by adopting the easiest method. This method enjoys the advantages of simple performance and accurate results.
