Popis:	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).
