Functional amphiphilic oligomers were synthesized and could be easily used to coat monodispersed hydrophobic magnetite Fe3O4 superparamagnetic nanoparticles (MSPNPs) with 13 nm diameter. The resulting hydrophilic modified MSPNPs (M-MSPNPs) with abundant groups on the surface, which could bond with Hg2+, exhibit excellent ability in the fast, efficient and selective removal of Hg2+ from water samples by low-field magnetic separation.
