| titleOfInvention | A kind of minusing measures the method for magnesium metal content in briquetting modulizer |
| abstract | The invention discloses a kind of method that minusing measures magnesium metal content in briquetting modulizer, wherein use magnesium metal in acetic acid,diluted dissolved samples, wash after filtration, insolubles drying is weighed.Pipette the filtrate of certain volume, take sodium tungstate as indicator, ferric iron Restore All is that divalence is to generating " tungsten blue " by titanium trichloride, with the reductive agent that rare potassium bichromate solution oxidation is superfluous, in sulfuric-phosphoric medium, take diphenylamine sulfonic acid sodium salt as indicator, with potassium dichromate standard solution titration ferrous iron, calculate the massfraction of iron in filtrate.To be dissolved by acetic acid,diluted in sample and the massfraction reduced deducts the massfraction of iron in filtrate is the content of magnesium metal.The present invention has simple and quick, accuracy and precision advantages of higher, meets the requirement of assay before metallurgical furnace completely. |
