Magnetic nanoparticles of Fe3O4@SiO2 have been extensively investigated as advanced adsorbents; however, most studies on surface modification of Fe3O4@SiO2 substances were of environmentally inefficient grafting methods, especially thiol functional group as adsorption agent for heavy metals [1-3]. Now, we demonstrated that magnetic nanoparticle of Fe3O4 to Fe3O4@SiO2 nanomaterials and then preparation of the Fe3O4@SiO2-SH can be facilely prepared by co-condensation of TEOS with Fe3O4 and then adding of propylthiol silane (PrSH).
In order to eliminate heavy metals such as Pd ions in polluted water, various methods have been developed, including chemical precipitation, ion exchange, adsorption, membrane, coagulation and flocculation, flotation, and electrochemical treatment [3].
