摘要
In this study, a novel magnetic core–dual shell Fe3O4@PDA@TiO2 adsorbents was successively prepared by polydopamine (PDA) coated and TiO2 film deposited on the surface of Fe3O4. The structure and properties were characterized by FT-IR, SEM–EDS TEM, VSM and XPS. The adsorption of U(VI) on Fe3O4@PDA@TiO2 was investigated as a function of contact time, solution pH, initial U(VI) concentration and other interfering ions. In addition, the U(VI) adsorption from practical wastewater and simulated seawater was also investigated. The results implied that the Fe3O4@PDA@TiO2 adsorbents exhibited promising adsorption performance for uranium (VI) from aqueous solution and simulated seawater.
