Abstract：Several common magnetic nanoparticles, such as magnetite, magnetic hematite and MFe2O4 ferrites, as well as their preparation and functionalization methods were introduced. The latest research progress of magnetic nano-adsorbents in heavy metal wastewater, dye wastewater, oily wastewater and phenolic wastewater was reviewed. And according to the problems existing in the research process, the future development trend of magnetic nanomaterials was summarized and prospected. In the future, the preparation process, adsorption mechanism, regeneration and reuse of magnetic nano-adsorbents can be further explore, in order to give full play to its application potential in practical industrial wastewater treatment.
