New functional materials for heavy metal sorption: "supramolecular" attachment of thiols to mesoporous silica substrates

Chem Commun (Camb). 2008 Nov 21:(43):5583-5. doi: 10.1039/b810576f. Epub 2008 Sep 26.

Abstract

A new class of sorbent material, which exhibits exceptional metal capture from contaminated natural water, features aromatic thiol ligands reversibly bound to functionalized mesoporous silica through non-covalent interactions and have the potential of being regenerable.
