Adsorption of agricultural wastewater contaminated with antibiotics, pesticides and toxic metals by functionalized magnetic nanoparticles

Functionalized magnetic nanoparticles (MNPs) as new-generation adsorbents have been widely used in environmental problems treatment processes due to their unique physical and chemical properties. MNPs has excellent efficiency towards the elimination of pesticides, antibiotics as well as toxic metals in agricultural wastewater because various specific functional groups anchoring the surface of magnetic nanoparticles, which can efficiently remove contaminants. Herein, this work aims to: (i) summarized the literatures about the sorption of pesticides, antibiotic and toxic metals; (ii) discussed the sorption mechanism and influence factors; (iii) pointed out prospective research necessities and challenges on the adsorption of agricultural wastewater pollutants by MNPs. To make feasibility of MNPs at large scale application, more efforts should be made to afford the relevant research in this field.
