Abstract
Heavy metals are environmental pollutants that affect air, water, and land because
of highly toxic and recalcitrant nature. Due to their adverse impacts on the natural
environment and human health, there is dire need for their eradication. Various
remediation technologies were employed for clean up the environment which
includes chemical coagulants, electrochemical, photocatalytical oxidation, ion
exchange, etc. Among all of these, nanotechnology is the most suitable approach
for the remediation because of its enhanced properties encompasses high surface
area to volume ratio disposable quality, high reactivity which offers a profound
potential remediation of environmental contaminants. This chapter summarizes
recent nano techniques employed for the removal of elimination of heavy
material.
