Heavy metal ions in drinking water have seriously effects on the people’s health, and adsorption is one of the most efficiency ways to removal of them. Traditional adsorbents (such as active carbon, active aluminum oxide) cannot meet the application requirements owing to the poor adsorption capacities. In recent years, many nanostructured materials have been developed based on the particular surface and interface properties of nanomaterials, and their show highly potential applications in the removal of heavy metal ions by adsorption. We plan to fabricate nanostructured materials with high surface area and abundance of surface groups to enhance the effective adsorption capacities. We also plan to do thoroughly research in order to revealing the adsorption mechanism between nanostructured materials and heavy metal ions by using the ultrahigh resolution of synchrotron radiation X-ray, combined with surface analysis and structure analysis. We also do some practical application research to treat the real underground water with nanocomposites fabricated by the programmed assembly method.
