Abstract:
This research was focused on the development of new iron oxide nanoparticles functionalized with cetyltrimethylammonium bromide (FO-CTAB) by an adapted coprecipitation method for environment remediation. For this scope, the physico-chemical characteristics of obtained FO-CTAB nanoparticles were x-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM) and X-ray diffraction (XRD) measurements. The results of our studies revealed that the FO-CTAB particles were obtained at nanometric scale (DTEM=20.88 ±1.5 nm) exhibiting a spherical morphology. On the other hand, the results of XRD studies highlight the presence of a cubic phase Fd-3 m of Fe3O4 in the studied sample. Furthermore, the results of the adsorption batch experimentsthat FO-CTAB samples were favourable for the adsorption of As(III) ions from aqueous solutions. Finally, the biological properties of FO-CTAB were studied by in vitro and in vivo test.The results of the in vitro cytotoxic assays obtained after24 h of incubation of FO-CTAB samples, showed that the studied sample did not alter the morphology of the HeLa cells and neither their proliferation.Moreover, the results of the histopathological studies conducted on various organsprelevated from the rats that have been feed with the water obtained after the As(III) decontamination (using the FO-CTAB), did not show any major alteration of the studied organs architecture. In conclusion, we could say that FO-CTAB samples could be excellent candidate’s environment remediation applications.
