Abstract—In the current project, V₂O₅ extraction from fuel fly ash was carried out, and the advanced extraction method was investigated. This reduced the percentage of industrial fuel fly ash residue pollution in the environment. The project was done with two materials: V₂O₅ and fuel fly ash. The extraction method includes alkaline leaching, pH regulation, ammonium compounds addition, and calcination. The experiment was identified using V₂O₅ as the primary material. Under the optimum amounts, the extraction efficiencies of V₂O₅ reached 92.9%, 92.9%, 99.6%. moreover, V₂O₅ eliminated over 90% of fuel fly ash. The obtained products were characterized using X-ray powder diffraction (XRD), Alkaline fusion-ICPMMS, Ultraviolet-visible (UV-Vis), and Fourier Transform infrared (FT-IR).
