Exposure to heavy metals is believed to cause toxic health effects in human and other life
forms on earth, even at trace level. Thus, effective removal of those undesirable metals from
water systems is still a very important and challenging task. The burgeoning demand for
clean water has led to the innovation of different nanomaterials for the fast and efficient
removal of pollutants and heavy metals (eg, arsenic, cadmium, copper, lead, chromium) from
water. Nanomaterials possess high heavy metal removal capacity from wastewater over …

Water treatment technologies are explored around the globe by various research groups for
sustainable access to clean water. Water gets polluted by manmade activities mainly
through industrial discharge. Heavy metals are one of the primary pollutants that are
discharged from tanning, electroplating, etc. Adsorption is the primary most preferred
technique for wastewater treatment. Nanomaterials as adsorbents have attained attention in
current years for their sustainability and ease of operations. Nanomaterials as composites …
