Magnetic nanoparticle-based nanocontainers for water treatment

Abstract A large number of chemicals intruded into the environment in the form of dyes, pesticides, and heavy metals have become a prime cause of water pollution. The removal of organic and inorganic matter from water through adsorption is the major and widely used step in conventional water treatment processes. Recently, various magnetic nanoparticle-based nanocontainers have been developed for effective removal of a wide range of water pollutants. Magnetite nanoparticles represent the most promising materials with good adsorption efficiency for water remediation applications, which on further modification with carbon-based materials such as carbon nanotubes, graphene, calixarenes, β-cyclodextrin, polymer, and bio-based materials exhibit enhanced malleable competence. In this chapter the recent development in magnetite nanoparticle-based nanocontainers has been discussed in brief, and their application in water remediation has been demonstrated.
