Recovery and Separation of Vanadium and Chromium by Two
Vanadium, chromium, and their oxides are widely used in many fields due to their excellent properties. In a vanadium plant, wastewater containing CrO 4 2– and VO 4 3– is generated and the vanadium–chromium reducing residue is formed via the reducing treatment of these wastewaters. Thus, vanadium and chromium in the residue exist almost as V(III) and Cr(III).
