主　　题：Mercaptopropyl MCM-48 absorbent mercury ions. 

摘      要：Mercaptopropyl groups were grafted onto the pore walls of mesoporous molecular sieves MCM-48. The pore structures were characterized by powder X-ray diffraction and N2 adsorption analYSiS. Elemental analysis confirmed that the material with high organic moiety （2.2 mmol/g） had been obtained. ^13C MAS NMR verified the tethered organic groups. The thiol-functionalized MCM-48 showed effective capture of mercury ions, and all of the organic ligands were accessible for the binding of mercury ions.
