An adsorbent was developed from the residues of Moringa oleifera Lam. seed husks functionalized with iron nanoparticles for subsequent application to the removal of metformin from contaminated water. The material, MOM-Fe3O4, was characterized using TEM, SEM imaging, and EDX analysis, which revealed that iron nanoparticles were retained in the pores. The application of MOM-Fe3O4 to waste water resulted in a 93.9% reduction in the metformin content, demonstrating the efficacy of the material. Kinetic and equilibrium data were fitted to the pseudo-first-order and Langmuir models, respectively. The thermodynamic parameters indicated an exothermic and reversible process. A high adsorption capacity, 65.01 mg g(-1) at 298 K, demonstrated the potential of using the new material as a low-cost adsorbent for the removal of pharmaceuticals such as metformin.
