The surfactants Fe(AOT)2 and Ni(AOT)2, prepared by replacing the Na+ ions of NaAOT with Fe2+ and Ni2+ respectively, were used as precursors in the synthesis of Fe3O4 and NiFe2O4 nanoparticles. FTIR and MS results confirmed the ionic substitution, having a molecular mass similar to the theoretical va...
