Organofunctional Sol-Gel Materials for Toxic Metal Separation

OSTI ID:826221
Inorganic-organic silica sol-gels grafted or encapsulated with organic ligands were prepared and found to selectively and reversibly remove target metal ions such as Cu2+, Cd2+, and Sr2+. These organofunctional sol-gel materials, which were easily prepared from off-the-shelf chemicals, were hydrophilic and showed fast kinetics of metal uptake. The sol-gels were easily regenerated and used in multi-cycle metal removal. In our search for new ligands for metal removal, we found that the reactions of thioacetal ligands with Hg2+ gave Hg(SCH2COOH)2. Our studies of organofunctional sol-gel materials for metal separation will be discussed.
