Removal of Organophosphorus Pesticides from Aqueous Solution by Magnetic Fe3O4/Red Mud‐Nanoparticles
The aim of this study was to investigate the usability of magnetic Fe3O4/red mud nanoparticles (NPs) for the removal of organophosphorus pesticides from water samples. The effect of various experimental parameters such as red mud amount in Fe3O4/red mud‐NPs, pH, contact time, initial pesticide concentrations and adsorbent dose was studied in order to find the optimum conditions for their removal in a batch process. The Fe3O4/red mud‐NPs were characterized by using TGA, SEM, XRD, VSM, and determination of the BET surface area. After the regenerated Fe3O4/red mud‐NPs were used three times, the sorption capacity and the magnetic separability were observed to be unaffected. Freundlich model described the sorption process better than Langmuir isotherm and the pseudo second‐order kinetic model was determined as the best‐fit model. The film diffusion mechanism was found to be a main rate control mechanism. The Fe3O4/red mud‐NPs satisfactorily removed the OPPS from real water samples.
