Abstract
Magnetic nanoparticles (MNPs) are gradually gaining attention as promising materials for environmental applications. The unique physicochemical properties of MNPs, especially their large surface areas, ease of synthesis and modification, and inherent superparamagnetic properties, could lead to improved technologies. This chapter evaluates recent developments in the use of MNPs to address environmental issues: the removal of various contaminants by adsorption, including organic and inorganic contaminants; the reduction of pollutants, such as photocatalytic materials and the components of mixed membrane matrixes; and the separation of biomass. In addition, the effects of MNPs on the environment are discussed. This chapter assesses the usefulness of MNPs in environmental applications and their potential environmental impacts.
