BiVO4 obtained after appropriate heat treatment can be sold as a pigment. The yield of recovery of solubilised vanadium is equal to 68% and the precipitate is free from nickel impurity. The precipitate is insoluble in the solutions with pH ≥ 3. In more acidic media the solubility of precipitate increases with the decreasing pH. The solubility of the precipitate increases also with the increasing concentration of chloride ions.}, type={Article}, title={Separation and Immobilization of Vanadium from Industrial Fly Ash as an Insoluble Inorganic Pigment}, URL={http://czasopisma.pan.pl/Content/116074/PDF/AMM-2020-2-51-Wojnicki.pdf}, doi={10.24425/amm.2020.132837}, keywords={recovery, inorganic pigments, solubility, vanadium, bismuth, immobilisation}, }
