| titleOfInvention | Method for detecting calcium and magnesium in sintered ore |
| abstract | A method for detecting calcium and magnesium in a sinter belongs to the field of metallurgical chemical analysis. The method for detecting calcium and magnesium in the sinter comprises the following steps: mixing and dissolving a sinter sample and hydrochloric acid, then adding stannic chloride, boiling and dissolving to a nearly dry state, then adding glacial acetic acid and water, boiling, cooling to room temperature, adding a copper reagent, reacting, fixing the volume, and then filtering to obtain a filtrate. Titration of calcium oxide: mixing the filtrate with water, triethanolamine and potassium hydroxide solution, adding calcium indicator, titrating to blue by using ethylenediamine tetraacetic acid standard titration solution as an end point, and determining the content of calcium oxide in the sinter sample. Titration of magnesium oxide: mixing the filtrate with water, triethanolamine and ammoniacal buffer solution, adding a chrome black T indicator, titrating to blue by using an ethylenediamine tetraacetic acid standard titration solution as an end point, and determining the content of magnesium oxide in the sinter sample. The method can accurately detect the content of calcium and magnesium in the sinter. |
