| Abstract: | The magnetic nanoparticles were prepared by co-precipitation and the received Fe_3O_4 were coated by silica on the surface.The functional magnetic nanoparticles(Fe_3O_4@ SiO_2)have many advantages,such as chemical stability,strong adsorption and especially excellent recycling capability.The ability of Fe_3O_4@ SiO_2 to remove dye from aqueous solutions has been carried out as function of solution pH,temperature,and contact time.The results show that Fe_3O_4@SiO_2 magnetic nanoparticles would be as low-cost and effective adsorbents for removal of methylene blue from wastewater. |
