摘要
为了弄清铸铝中的铁含量，通过实验并绘制了铁的吸收曲线和工作曲线，并对干扰元素进行实验，与原子吸收分析方法所得的结果进行比较，测定了回收率，并计算了精密度、相对偏差、标准偏差，对试样１０７铸铝用邻菲序啉比色法进行了测定。叙述了完整的分析程序。
Iron-absorbing cruves and operating curves are drawn through experiments to find of out iron content in cast aluminium .An experiment for interference elements is done .Comparing the results with that obtained by analysis for atom-absorption ,measuring rate of recovery ,and calculating precison ,relative deviation and standard deviation .A sample .107 cast aluminium is measured by 1. 10-Phenanthroline colorimetric method .A complete analyzing program is described .
