| 英文摘要 | Removal of heavy metal ions from aqueous solution for water purification through nanoadsorbents has been of great interest. However, the removal capacity and efficiency are still non-ideal due to some issues such as the agglomeration among adsorbents which severely reduces the adsorption sites. We present a potential strategy for developing adsorbents through surface modification on a specific three-dimensional (3D) nanostructure for adsorbing Pb(II) and As(V). A 3D hierarchical nanostructure which consists of a coral-like SnO2/C base and a dense MgSiO3 nanoflake coating on the surface was prepared through a two-step hydrothermal route. The 3D MgSiO3-coated SnO2/C nanostructure exhibits maximum adsorption capacities of about 185 and 109 mg g(-1) to Pb(II) and As(V), respectively. Impressively, the MgSiO3-coated SnO2/C has a higher removal efficiency than the SnO2/C without MgSiO3 coating, MgSiO3 nanostructure, and the commercial active carbon. Good chemical and mechanical stability of the presented nanostructure is also confirmed by the characterization of the post-adsorbing adsorbents. In addition, a common stick coated with the presented nanoadsorbents was proposed and preliminarily used for heavy metal ion adsorption, exhibiting a promisingly simple method for water purification. |
