| titleOfInvention | For the chemical analysis method measured containing zirconium content in multiple interference element alloy |
| abstract | A kind of chemical analysis method for measuring containing zirconium content in multiple interference element alloy, it is characterized in that comprising the steps: to adopt platinum ware, add nitric acid, hydrofluorite and sulfuric acid alloy sample is dissolved, interference element is separated with NaOH, be in the hydrochloric acid medium of 1.25 moles often liter in hydrogen ion volumetric molar concentration, at 90 DEG C ~ 100 DEG C temperature, take xylenol orange as indicator, with the zirconium in EDTA titration precipitation.The invention has the advantages that: be particularly applicable to wearing the mensuration of firing difunctional alloy zirconium content, measurement result is accurate, measures process convenient. |
