Claims22
A porous alumina-carbon nanotube membrane comprising at least about 90 wt. % Al2O3 and between about 0.5 wt. % and about 5 wt. % carbon nanotubes.
A method for making a porous alumina-carbon nanotube membrane comprising sintering a mixture comprising at least 90 wt. % Al2O3 and between about 0.5 wt. % and about 5 wt. % carbon nanotubes.
A method for removing a heavy or toxic metal from water comprising contacting an aqueous solution containing cadmium, which has a pH ranging from 5.5 to 8.5, by contacting the aqueous solution with a porous alumina-carbon nanotube membrane that comprises at least about 90 wt. % Al2O3 and between about 0.5 wt. % and about 5 wt. % carbon nanotubes, and recovering water from which the heavy or toxic metal has been removed.
