【 摘 要 】

The objective of this program is to rationally design and synthesize imprinted sol-gel SiO2 and SiO2-MO2 (M = Ti, Zr) materials containing Si-X-L binding groups through template approaches and develop a scientific basis for metal ion binding and recognition by such tailored hybrid inorganic -organic materials. These hydrophilic oxide-based materials are expected to remove metal ions from aqueous solutions intrinsically fast (in comparison to hydrophobic organic polymers), and the imprinted binding sites are expected to exhibit enhanced recognition and binding of target RCRA metal ions.
