Thiol-functionalized MCM-48: an Effective Absorbent of 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.
