摘要
通过试验,建立了测定磁铁原矿中铁的分析方法,试样经磁石吸附洗涤,盐酸分解,盐酸羟胺还原,邻菲罗啉显色后,在510nm波长处有一最大吸收波长。并讨论了测定条件对结果的影响。该方法已用于实际样品的测定。。
This paper illustrates establishing analysis means of the measurement for iron content in ferromagnet crudes by means of experiment. After the specimen are washed through the magnetite sticking,and hydrochloric acid decomposition, and hydrochloric acid Qiang＇s amine reduction, and o-phenanthroline color rendering queen of neighbour, the greatest absorption wavelength exist in the 510 nm wavelength point. This means has been used in actual specimen measurement.
