Abstract
Magnetic nanoparticles (MNPs) possess inherent properties that help them
in improving the quality of the environment via the detection, remediation, and
removal of pollutants and contaminants. The properties such as high reactivity, high
surface-to-volume ratios, superparamagnetism, large surface area and biocompatibility
are responsible for the extensive use of magnetic nanoparticles in environmental
remediation. MNPs act as adsorbents or catalysts and help in the removal of
contaminants from environmental matrices. High pollutant removal efficiency of
magnetic nanoparticles can be exploited in framing low-cost-effective technologies for
environmental remediation.
