Recovery of Vanadium by ammonium chloride precipitation method using response surface methodology
Volume 4, Issue 04, Pages 64-77, Dec 2021 *** Field: Analytical Chemistry
Abstract
In this study, an attempt was made to recover vanadium from an alkaline solution using the precipitation process. A white salt ammonium metavanadate was obtained using the ammonium chloride precipitation method. Ammonium chloride was added directly to the alkaline liquor solution and the pH was adjusted approximately between 5 and 7 to form the white salt. The parameters affecting the recovery of vanadium, including the ammonium chloride concentration, the pH and the vanadium concentration in the caustic solution, were examined. The precipitation time had no significant influence on the vanadium recovery. The concentration of vanadium in the caustic solution and the concentration of ammonium chloride used for the precipitation were inversely related. It was found that a high recovery (over 90%) can be achieved with ammonium chloride and vanadium with concentrations over 4% (w / v) or 1000 mg L-1 (in the lye solution). It has also been observed that working in the pH range of 5 to 7 results in over 90% recovery. The influence of the parameters mentioned on the recovery of impurities was examined and the optimal values determined. Ultimately, the maximum vanadium recovery (97.29%) was achieved at the optimal point obtained from the reaction surface methodology.
