The recent advances of MnFe₂O₄-based nanoparticles in environmental application: A review

The manganese ferrite (MnFe₂O₄)-based nanoparticles showed a substantial potential to remediate the various pollutants in environmental application due to low cost, simple magnetic separation and high removal capacity. Herein, the functionalization of various MnFe₂O₄-based nanoparticles was briefly summarized; Then the recent advances concerning the removal of pollutants (i.e., organics, heavy metals and antibacterial activity) on different MnFe₂O₄-based nanoparticles were reviewed in details. The reactivity of MnFe₂O₄-based nanoparticles was significantly influenced by environmental factors. It is demonstrated that interaction mechanism of various pollutants on magnetic MnFe₂O₄-based nanoparticles included degradation, adsorption, coordination, redox and precipitation. Finally, the current problems and future perspective of MnFe₂O₄-based nanoparticles were proposed. The highlight of this review is to compare the removal performance of MnFe₂O₄-based nanoparticles with the different hybrids. This review is crucial for the application of MnFe₂O₄-based nanoparticles in the environmental remediation.
