Production of metal oxide nanoparticles through solvent extraction and crystallization stripping

In this work, the extraction of vanadium from alkaline solution, and the production of metal oxides through precipitation stripping, were carried out. The crystallization of calcium, copper, and iron vanadates from the extracts was performed using a solution containing a metal source as a stripping agent. In some experiments, a stabilizing polymer for controlling growth and avoiding agglomeration was added to the stripping solution. The structural characteristics of the crystallized products were studied. From the results, the synthesis of nanostructured vanadates is a simple and versatile method for the fabrication of valuable vanadium compounds.
