Magnetic Nanoparticles for Environmental Management

Abstract

Magnetic nanoparticles are an emerging technique that has attracted attention in recent years in nanotechnology, biomedical, electronics, environmental science, and engineering applications. Nanoparticles have optical, electrical, catalytic, and thermal properties with their supermagnetic properties, large surface area, and biocompatibility. The major benefit of using nanoparticles is that due to their size, they can be accurately oriented and can be targeted and interacted with a specific biological entity or marker. In addition, it is easy to separate the magnetic property from the aqueous solution with the application of an external magnetic field. From an environmental perspective, MNPs have been used as catalysts in the purification of whey; removal of heavy toxic metals such as Arsenic (As), Lead (Pb), and toxic pollutants such as Fluoride (F) from contaminated water; and photocatalytic degradation of dyes and pollutants in water. In this study, types of magnetic nanoparticles, synthesis methods, properties, and environmental science and engineering applications are included.
