Magnetic Separation of Pollutants for Environmental Remediation

Abstract

Magnetic adsorbents are composed of magnetic materials for magnetic separation and functional molecules for adsorption of substances. Depending on the properties of the functional molecules used, it is possible to adsorb various pollutants such as harmful organic compounds, heavy metals, and radioactive substances. The selectivity, rate, conditions, and maximum amount of adsorption depend on the material used and its design of adsorbents. This chapter summarizes the adsorption characteristics of pollutants in environmental samples for three types of adsorbents: surface-modified magnetic adsorbents, magnetic polysaccharide composites, and functionalized natural magnetic materials.
