| titleOfInvention | The preparation of a kind of ammonium metavanadate and purification process |
| abstract | The invention belongs to chemosynthesis technical field, it is provided that the preparation of a kind of ammonium metavanadate and purification process, be adjusted pH value and except the impurity such as iron, titanium with NaOH solution, EDTA, ammoniacal liquor, HF solution the most successively.Optimal synthesis condition is: NH 4 Cl and NaVO 3 Reactive chemistry metering ratio is 5, and pH value in reaction 8.0 9.0, in 45 minutes reaction time, reaction temperature is 70 80 DEG C.The inventive method process is simple, low cost, favorable reproducibility.Particularly generate the complexing material of solubility with EDTA and HF Complexing Iron respectively and titanium, to reach the purpose of removal of impurities. |
