Abstract
Disclosed herein is a nanostructured material comprising defective carbon nanotubes chosen from impregnated, functionalized, doped, charged, coated, and irradiated nanotubes, and combinations thereof. The defective carbon nanotubes contain a defect which is a lattice distortion in at least one carbon ring. Also disclosed is a method of purifying fluids, such as liquids, including water, as well as gases, including the air using, this nanostructured material.
Claims21
An article for reducing or removing at least one contaminant from a fluid, said article comprising:
- (a) a filtration media comprising:
- carbon nanotubes having at least one functional group attached thereto, and a support medium for said carbon nanotubes, wherein a plurality of said carbon nanotubes are fused or bonded to said support medium, to another carbon nanotube, or to a combination thereof, and
- (b) an assembly containing said filtration media.
A method of reducing or removing at least one contaminant from fluid, said method comprising passing fluid through an article comprising:
- (a) a filtration media comprising:
- carbon nanotubes having at least one functional group attached thereto, and a support medium for said carbon nanotubes,
- wherein a plurality of said carbon nanotubes are fused or bonded to said support medium, to another carbon nanotube, or to a combination thereof, and
- (b) an assembly containing said filtration media,
- wherein said filtration media is positioned in said assembly such that the fluid passes through or adjacent to said filtration media to capture said at least contaminant in said filtration media,
- wherein said at least one contaminant is chosen from salts, metals, pathogens, microorganisms, DNA, RNA, natural organic molecules, molds, fungi, natural and synthetic toxins, endotoxins, proteins, and enzymes.
