Dephosphorization of Vanadate Leaching Solution by Chloride-Free Dephosphorizing Agent
International Journal of Chemical Engineering and Applications, 2013 CaCl2 was generally used as dephosphorizing agent during the sodiumization-vanadium extraction process. However, a large number of chloride ions were brought into wastewater from vanadium precipitation, which increased the corrosion of the evaporation-concentration equipments of wastewater treatment. Then, the chloride-free dephosphorizing agent (CFDA)
