Original Abstract

Surfactants coated magnetic nanoparticles have shown greater application potentials in freshwater source treatment processes for their antibacterial properties.In this work, we prepared magnetic nanoparticles Fe3O4 which surface were modified with Cethyltrimethylammonium bromide (CTAB), tetradecyltrimethylammonium bromide (TTAB) and Carbaethopendecine bromide (Septonex), respectively. Their physicochemical properties and morphology were investigated using thermal analysis (i.e. elemental and thermogravimetric analysis), infrared spectroscopy with Attenuated Total Reflectance (ATR-FTIR), dynamic light scattering (DLS) and transmission electron microscopy (TEM).The highest surfactant content was obtained for Fe3O4 nanoparticles coated with Cethyltrimethylammonium bromide. The presence of –CH2–, –CH3 and ammonium salt functional groups in infrared spectra implied that all surfactants had been successfully anchored onto the surface of native Fe3O4 nanoparticles. All modified nanoparticles were surface charged and they not tended to agglomerate in deionize water. The highest value of zeta-potential (approximately 40 mV) was obtained for Fe3O4-TTAB. Another characteristic coefficient is polydispersity index (PDI) its relative value was comparable for all modified nanoparticles. The transmission electron microscopy (TEM) analysis showed all modified nanoparticles were approximately spherical morphology with the core size in the range 5–15 nm.
