Removal of sulfadiazine from aqueous solution by magnetic biochar prepared with pomegranate peel

Abstract

Magnetic biochar (Fe₃O₄-BCPP) was prepared by using iron oxide nanoparticles, and biochar which is obtained from pomegranate peel. The Fe₃O₄-BCPP were characterized by Brunauer-Emmett-Teller analysis, X-ray diffraction analysis, scanning electron microscopy, and vibrating sample magnetometer. The adsorption properties of Fe₃O₄-BCPP for sulfadiazine in water were investigated. The Fe₃O₄-BCPP had good adsorption properties and separated well from aqueous solution by a permanent magnet due to superparamagnetic property and magnetic saturation value. Therefore, Fe₃O₄-BCPP has potential application for the removal of sulfadiazine from water samples.
