Abstract
Nanotechnology is a multidisciplinary i eld that has gained signii cant momen-
tum in recent years. Nanoparticles are the key players that promised many ben-
ei ts through their nano-enabled applications in multiple sectors. h e success of
the technique in i eld conditions is a factor of the interdisciplinary work that is
involved. Nanoremediation has the potential to clean up large contaminated sites
in situ , reducing clean up time and eliminating the need for removal of contami-
nants, and hence reducing the contaminant concentration to near zero. h e explo-
sive growth in nanotechnology research has opened the doors to new strategies
using nanometallic particles for extraction of pollutants. h is chapter briel y deals
with recent advances and applications of nanotechnology for removal of environ-
mental pollutants. Under the nanotechnology umbrella, a number of new proce-
dures for producing nanomaterials ultimately used for treatment of wastewater
are presented. Research advances for the use of metals, bimetallic nanoparticles,
mixed oxides and carbon nanomaterials in environmental remediation are also
reviewed.
