DOI: 10.1021/acs.est.9b06250
Abstract: Vanadium contamination is a growing environmental hazard worldwide. Aqueous vanadate (HxVVO4(3-x)- (aq)) concentrations are often controlled by surface complexation with metal (oxyhydr)oxides in oxic environments. However, the geochemical behaviour of this toxic redox sensitive oxyanion… read more here.
