Electrospun Pineapple Leaf Fiber/MIL-101(Fe)-NH₂-Cyclodextrin nanofibrous membranes for enhanced and selective removal of contaminants from Wastewater
Pharmaceutical contamination of wastewater poses a significant threat to aquatic ecosystems and human health. Traditional wastewater treatment methods often struggle to effectively remove these emerging contaminants. This study investigated the potential of MIL-101(Fe)-NH2-Cyclodextrin nanofibers as a novel adsorbent for removing pharmaceutical contaminants from wastewater. The performance of this material was compared to traditional Electrospun Pineapple Leaf Fiber, an alternative bio-based adsorbent. MIL-101(Fe)-NH2-Cyclodextrin nanofibers exhibited significantly enhanced adsorption capacity and kinetics compared to Pineapple Leaf Fiber. For example, at an initial concentration of 100 mg/L and pH 7, MIL-101(Fe)-NH2-Cyclodextrin nanofibers achieved a removal efficiency of 96 ± 2% for Ciprofloxacin, while Pineapple Leaf Fiber only achieved 65 ± 3.5%. This superior performance is attributed to the material’s high BET surface area (1220 m2/g) and broad pore size distribution, providing a vast surface area for contaminant adsorption and an intricate network for trapping contaminants as well as cyclodextrin-functionalized active sites, which enhance host-guest interactions and hydrogen bonding. Furthermore, MIL-101(Fe)-NH2-Cyclodextrin exhibited faster adsorption kinetics, achieving equilibrium within 60 min for Ciprofloxacin, compared to 120 min for Pineapple Leaf Fiber. These findings suggest that MIL-101(Fe)-NH2-Cyclodextrin nanofibers offer a promising alternative to traditional adsorbents for removing pharmaceutical contaminants from wastewater. Its high removal efficiency, fast kinetics, and potential for reusability make it a valuable tool for addressing the increasing issue of pharmaceutical pollution in aquatic environments. Further research is needed to optimize its performance and assess its feasibility for real-world applications, but this study offers a compelling roadmap for developing innovative and effective solutions for safeguarding our water resources.
