[Determination of manganese in ore by extraction-photometric method of I2-CCl4 with ammonium peroxodisulfate as oxidizer].
Ore samples were resolved by ammonium peroxodisulfate, and Mn (II) contained in the samples was oxygenated into Mn (VII), which in turn reacted on KI, separating out I2. According to the above experiment, manganese was then determined indirectly by the use of extraction photometric method of I2-CCL4 and satisfactory results have been obtained. When manganese content is between 0.001-0.1 mg.L-1, observe the law of "bier" and, compare with the experimenting method of the rate of reclamation and the other determination method, the excellent result has been got and its rate of reclamation is between 97%-103%.
