摘要
提出了以高氯酸代替经典方法中的二氯化汞氧化过量的氯化亚锡 ,重铬酸钾标准溶液滴定 Fe2 +的无汞盐测定铁矿石中全铁的新方法 .用该法测定了铁矿石中的铁含量 ,其相对标准偏差为 0 .0 9% ,且测定结果与经典法非常一致 .
The new method was advanced to determine iron of the iron ore.In the method,mercuric chloric solution of the classical method was replaced with perchloric acid solution to oxide the little excess stannous chloride and Fe 2+ was titrated with potassium dichromate standard solution.The method was been applied to determine iron of the iron ore with the relative standard deviations of 0.09%. The results compare with classical method.
