Abstract
Clean, secure, and adequate water is basic to the endurance of every individual living life frame. Environmental pollutants pose serious threats to freshwater supply, living organisms, and public health, despite their occurrence at low concentration ranges. Thus, treatment of waste water required around the creation. So, nanotechnology is an innovative technique for the treatment of water and wastewater to improve water quality and to improve water supply through safe usage of clean water source. Therefore, in past various techniques utilized for wastewater treatment, for example, adsorption, compound precipitation, sol–gel, solvo–thermal response, and so on, for the incorporation of nanoadsorbents, which can be viably utilized for groundwater treatment. This chapter concentrates on the removal of pollutants from water using a variety of adsorbents such as nanotubes, nano wires, and nanoadsorbents by using adsorption technology, which has turned out to be one of the best technologies for wastewater treatment. The survey will aid the readers to select suitable nanomaterials and to get up further research required for pollutant removal using nanoadsorbents, depending on the characteristics of effluents to be processed, industrial applicability, release standards, cost- effectiveness, regulatory demands, and durable ecological impacts.
