Copper Purging from Industrial Effluent by Adsorption using Fe3O/MnO2 Nanocomposites

Using chemical affinity, zero potentials, XRD, FTIR and TEM, this study examines the structure of Fe3O4/MnO2 composites and explores the mechanism of interface adsorption. The investigation extends to examining adsorption, desorption and recycling experiments. Cu (II) was extracted from industrial wastewater using repurposed magnetic sorbents. The study shows that the Fe3O4/MnO2 composites comprise two layers, one made of amorphous MnO2 and the other with Fe3O4 in the center. Because they replaced H in Mn-O-H to produce the structure of Mn-O-Me; heavy metals were removed from the solution using ion exchange. Cu was impressively removed by the sorbent with a 99.76% efficiency, demonstrating high removal efficiency of Fe3O4/MnO2 composites. The examination of equilibrium data led to the conclusion that the Langmuir model was the most appropriate for elucidating adsorption on the surface of Fe3O4/MnO2 composites. Kinetic studies revealed a strong alignment between heavy metal ion adsorption and the pseudo-second-order model of heavy metal ions on the surface of Fe3O4/MnO2 composites. This study proved that using an external magnetic field to extract water from Fe3O4/MnO2 sorbent for recycling was a practical and effective way to remove heavy metal ions.
