Metal–Organic Frameworks (MOFs) for Sustainable Water Disinfection: Synthesis, Characterization, and Antimicrobial Properties
J. Environ. Nanotechnol., Volume 13, No 2 (2024) pp. 238-247
Abstract
Waterborne biological pollution poses a significant threat to both the environment and human health, leading to the transmission of various waterborne diseases. Ensuring the safety of drinking water is essential for safeguarding public health and reducing the prevalence of waterborne illnesses caused by microbial pollutants. Recently, there has been a notable increase in the utilization of nanoparticles for water treatment purposes. Metal-Organic Frameworks (MOFs) are emerging as promising candidates for enhancing water treatment processes due to their structural and functional adjustability and makes them stand out for environmental remediation. Notable properties include porous structures with customizable sizes, large surface areas, and internal characteristics that are variable. In this study, zeolitic-imidazolate frameworks (ZIF-8) and Ag@zeolitic-imidazolate frameworks (Ag@ZIF-8) were synthesized using 2-methylimidazole (2-MIM) as an organic linker via a facile green synthesis method and used for water disinfection. These MOFs were characterized using a range of techniques including UV-vis spectroscopy, FTIR, and X-ray diffraction, SEM/EDS. The antibacterial activity of ZIF-8 and Ag@ZIF-8 were evaluated using the disc diffusion method against Gram-negative and Gram-positive bacteria, i.e., E. coli and S. aureus, respectively. These MOFs demonstrated strong antimicrobial activity against both Gram-positive S. aureus and Gram-negative bacteria E. coli, where the Ag-ZIF-8 MOF exhibited improved antibacterial activities over ZIF-8 alone. Finally, the suggested material shows promise for reusable water filtration and disinfection against a variety of pollutants, providing a practical option to reduce environmental and public health threats.
