Nanosorbents for heavy metals removal

Water scarcity is exerting pressure on sources providing water for human beings. Water contamination is a major issue in the current scenarios and is happening due to insufficient sewage management, industrial pollution, dumping in marines, etc. Water pollution is posing adverse effects on health of human beings. Removal of heavy metals from contaminated water is a major concern of scientists these days. Nanotechnology has been emerging and gaining interest to remove heavy metals from contaminated water. Nanomaterials have excellent characteristics including size to porosity, which made them valuable for wastewater treatment. In this chapter, we reviewed the efficacy of various nanomaterials including organic and inorganic for removal of wastewater pollutants. Keeping in view the efficiency of nanomaterials, their potential future perspectives have been also discussed.
