  • Metal remediation using a mesoporous nanocomposite
    Patent number: 7915475
    Abstract: A novel method for remediating metals includes treating the metals with a mesoporous nanocomposite such as HMS, MCM-41 or MCM-48. The metal is preferably lead but can be at least one metal selected from Pb, Hg, Cd, Zn, Sn, As, Sb, In, Se, Ga, Te, Bi, Ni, Cu, Mo, Ni, Cu, Sr, Ba or Co. The treating is preferably performed at a pH of about 4 to about 12. In the invention, the treating can also include desorbing the metal from the mesoporous nanocomposite at a pH of about 2 or less.
