原子吸收法白烟尘中铟的测定

原子吸收光谱分析中，采用标准加入法来测定样品中干扰难以排除的元素是行之有效的方法。基于此本文分别采用了王水溶样，王水一氟化铵溶样和碱熔样处理转炉白烟尘，通过对三种方法得到的数据评估后采用碱熔样，最终采用标准加入法测定转炉白烟尘的铟。本文详细介绍了采用Excel2006处理实验数据，很大程度上简化了计算与绘图。

The Method for Determination of Indium in White Soot from Converter by Standard Addition in AAS Analysis

Using the Standard Addition Method in AAS to analysis the sample with interferential elements difficult to be divided is one of the effective methods. Depending on that, the white soot from converter was dissolved in the system of aquaregia and aquaregia - ammonium fluoride, and by smelting with alkali. By evaluating the data from the three experiments, we decided to dissolve the sample by smelting with alkali at last and the indium in white soot was determined by using standard addition method. In the article, we introduce a method of using Excel 2006 to deal with the data form experiments, and the calculation and plotting are more comfortable than before.
