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).

通过萃取和去除五氧化二钒减少燃料粉煤灰的环境污染

摘要

在本项目中，从燃料粉煤灰中提取V ₂ O ₅，并研究了先进的提取方法。这减少了环境中工业燃料粉煤灰残留物污染的百分比。该项目使用两种材料完成：V ₂ O ₅和燃料粉煤灰。提取方法包括碱浸，pH调节，添加铵化合物和煅烧。实验以V ₂ O ₅为主要材料。在最佳用量下，V ₂ O ₅的萃取效率分别达到92.9％，92.9％，99.6％。此外，V ₂ O ₅消除了超过90％的燃料飞灰。使用X射线粉末衍射（XRD），碱性熔融-ICPMMS，紫外可见光（UV-Vis）和傅立叶变换红外光谱（FT-IR）对获得的产物进行表征。
