Abstract

Abstract: Inpresent paper the recovery of Mn-Zn ferrite nano-particles from waste batteries by using acid dissolution and ferrite process were studied. The recovered Mn-Zn ferrite nano-particles were decorated on rGO by using facile solvothermal method. The prepared material were characterized by X-ray powder diffraction (XRD) to study particle size and crystallinity, the morphology of the particles were analyzed by using Scanning Electron Microscopy (SEM), functional group were observed using Fourier Transform Infrared Spectrometer (FTIR) and band gap energy were examined by UV-Visible spectrometer. Graphene oxide used toeliminatethe pollutantspresent in the wastewater. The developed material used as an adsorbent for the removal of ionic dye in acid orange 88. The Mn-Zn ferrite nano-particles decorated with rGO showed a superior photocatalytic activity compared to that of Mn-Zn ferrite nano-particles.
