Magnetic graphene oxide (MGO) is an inorganic composite material composed of graphene oxide (GO) that has the characteristics of GO and magnetic material. The application of MGO in water treatment can effectively solve problems such as difficult recovery of the adsorbed GO from liquid, low efficiency, and high treatment cost, which are regarded as having important academic research value. In this study, the properties, synthesis approaches, and characterization methods of MGO, as well as its adsorption effect and the mechanism of this composite material as an adsorbent of heavy metals, organic dyes, and rare earth ions during water treatment, are comprehensively summarized. Finally, the future development of MGO as a high-efficiency adsorbent is discussed to provide references regarding application of MGO in the field of water treatment.
