Nanotechnology for the Remediation of Heavy Metals

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.
