Remarkable Separation of Carbofuran Pesticide from Aqueous Solution Using Free Metal Ion Variation on Aluminum-Based Metal-Organic Framework

The alarming increase in pesticide residues poses a major threat to aquatic and natural habitats. Therefore, it has become essential design extremely operationally economically advantageous systems for the removal of carbofuran pesticides from wastewater. Here, an aluminum-based metal-organic framework (MOF), MIL-53-NH2, its modified forms, MIL-53-NH-ph, MIL-53-NH-ph-Fe, MIL-53-NH-ph-Zn, MIL-53-NH-ph-Cu, have been successfully synthesized. Full characterization using IR, 1HNMR, XRD, SEM was carried out. prepared MOFs utilized as effective adsorbents aqueous solutions. various factors affecting adsorption process (pH, time, adsorbate concentration) were also investigated. Spectroscopic approaches used investigate mechanisms. A mixture π-π stacking contact, coordination bonding, hydrogen bond formation can be connected current process. solutions best described by pseudo-second-order kinetics Langmuir equilibrium isotherm models. MIL-53-NH-Ph, MIL-53-NH-Ph-Fe, MIL-53-NH-Ph-Zn, MIL-53-NH-Ph-Cu demonstrated capacities 367.8, 462.1, 662.94, 717.6, 978.6 mg g−1, respectively.
