The objective of this program is to rationally design and synthesize imprinted sol-gel SiO2 and SiO2/M'O2 (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 imprinted organofunctional materials. Removal of metal ions from aqueous solutions by hydrophilic metal oxide-based materials is expected to be fast in comparison to hydrophobic organic polymers and the imprinted binding sites are expected to exhibit enhanced selectivity and affinity of target metal ions
