Adsorption Isotherms of Carbon-Framed Magnetic Iron Oxide Nanoparticle Adsorbents in Selenium Contaminated Water

Demand for potable and irrigation water is increasing as the world population grows, however, contaminants present in water pose a safety risk. Selenium is naturally present in bodies of water but is highly toxic if concentrations exceed regulatory guidelines. Removal of selenium is primarily done through the use of adsorbents. Magnetic iron oxide nanoparticle adsorbents suspended within a tire-derived carbon framework (C-MNA) are compared with activated carbon adsorbents and their adsorption isotherms are modelled using a Freundlich fit.
