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.

12.7 Conclusions

The present chapter aims on the current progress associated with the desalination and heavy metal ion detoxification of water and wastewater using nanomaterials as nanoadsorbents. These nanoadsorbents were utilized for the removal of metal ions, organic compounds, and dyes from water samples. The adsorption capacities demonstrated in the various publications present effectiveness of the sorbent for the specific type of metal species which in turn depends on various experimental parameters. The utilization of nanomaterials, nanotubes, naowires, and naofilters for water and wastewater desalination and heavy metal detoxification presents excellent adsorption capacity toward metal ions, economic viability, nonhazardous nature, and biocompatibility. We imagine that nanomaterials will get to be distinctly basic parts of open water treatment and modern frameworks.
