| Abstract: | 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. |
