In this study magnetic nanoparticles were fabricated and used for water treatment. Nanoparticles were prepared in two ways. The first one involved NiZn ferrite nanoparticles synthesized by co-precipitation of metal cations with sodium hydroxide at high temperature. The second one featured maghemite nanoparticles was prepared by salt-assisted solid-state reaction. Modification and functionalization of nanoparticles surface was investigated. Nanoparticles were characterized by scanning electron microscopy (SEM). Modified nanoparticles were added to the solution of desired concentration of methylene green. Adsorption ability was examined trough ultraviolet-visible spectroscopy (UV-VIS). For NiZn ferrite and also for maghemite nanoparticles results were positive. Both of complexes can be used for water treatment with 51% success for maghemite and 72% for NiZn ferrite nanoparticles.
