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%.

The article studies that in dilute H2SO4 dielectric substance IO3(-) reacts with C2O4(2-) to release certain amount of iodine under certain reaction condition: 2IO3(-) + 5C2O4(2-) + 12H+ = I2 + 10CO2 increasing + 6H2O therefore the method of indirect determination with I2-CCl4 extraction spectrophotometry is established. The reaction temperature is controlled in 90 degrees C; the reaction time 3 minutes; the reaction acidity pH1.0-2.
