Abstract

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 Cu ²⁺, Cd ²⁺, and Sr ²⁺. These organofunctional sol-gel materials were hydrophilic and showed fast kinetics of metal uptake. The sol-gels were easily regenerated and used in multicycle metal removal. In our search for new ligands for metal removal, we found that the reactions of thioacetal ligands with Hg ²⁺ gave Hg(SCH ²COOH) ².
