Abstract
Contaminated water with heavy metals is considered to be a serious threat to human health as well as to the environment. Heavy metals get a great attention owing to their toxicity and persistence in the environment. Different techniques for elimination of heavy metal have discussed in literature. Adsorption, the most extensively used method; plays vital role in wastewater treatment. Many research studies have been taken place during the last decade for the preparation of effective and economically suitable adsorbents. More recently, nanotechnology and material science have opened a new way for the buildup of new materials that can be used for the elimination of different pollutants. This review includes analyzing and discussion of different research studies and research papers published during last ten years, concerning the usage of nanomaterials for omitting heavy metals from aqueous solutions.
Keywords
