Chapter 18 - Nanoparticles for the adsorptive removal of heavy metals from wastewater

Abstract

Nanotechnology is one of the most innovative and fascinating domains of science and technology. The application of nanotechnology to engineering enables creation of nanomaterials with unique qualities for a variety of engineering applications that have been established and used for human advancement. In the past few years, it has proved its ability to contribute to one of the most important environmental concerns, wastewater treatment. In recent years, several novel nanoparticle adsorbents have been proposed to improve the efficacy and adsorption capabilities of harmful contaminants from wastewater. The current research looks at using Nanoparticles as a nanoadsorbent to remove heavy metals from wastewater. The fundamentals of adsorption, as well as a variety of nanoadsorbents often utilized in wastewater treatment, are discussed in this work. The goal of this chapter is to highlight the importance of adsorption, various Nanoparticles synthesis methods and their application in the field of wastewater treatment.
