Abstract
A crucial issue is the development of highly and selectively absorbable pesticides. At room temperature, aluminum-based metal–organic frameworks (MIL-53-NH2, MIL-53-AZA, MIL-53-AZA-La, and MIL-53-AZA-Ce) were successfully formed. Using prepared MOFs as sorbents, carbofuran was adsorbed from wastewater. Experimental and spectroscopic studies were used to investigate the elimination mechanisms. The current process can connect a mixture of pi- pi stacking contact, coordination bonding, and hydrogen bond production. The adsorption of carbofuran from wastewater was best described by pseudo-second-order kinetics and Langmuir isothermal models. MIL-53-NH2, MIL-53-AZA, MIL-53-AZA-La, and MIL-53-AZA-Ce had elimination capacities of 367.87, 433.50, 610.23, and 635.05 mg g-1, respectively. The synthesized MOFs are represented as promising materials for the removal of carbofuran.
