A novel two-dimensional carbon-based magnetic nanomaterial, magnetic graphene oxide (MGO), was prepared and then used as an efficient adsorbent. MGO showed rapid and complete removal of iron(II) (Fe) and manganese(II) (Mn) from micropolluted water bodies over a wide pH range. After saturated adsorption, MGO could be rapidly separated from water under an external magnetic field. …

For example, when separating the iron, salt, and sand mixture we were able to use a magnet to remove the majority of the iron from the mixture. This form of physical separation works because even though the components are mixed together, they retain their own characteristics, so iron remained magnetic even though it was a part of the mixture.
