铁基MIL-88B-NH2纳米纤维素复合膜对环境水样中三唑类抗菌药物的高效吸附与去除
Highly Efficient Adsorption and Removal of Triazole Antimicrobial Drugs in Environmental Water Samples by Iron-based MIL-88B-NH2 Nanocellulose Composite Membranes
摘要
Abstract
Triazole-based antimicrobial agents,as emerging contaminants,pose a significant threat to aquatic ecological safety.In this study,an innovative composite membrane adsorbent named Fe-MIL-88B-NH2@TOCN@PVP was fabricated by integrating iron-based metal-organic framework(Fe-MIL-88B-NH2)with TEMPO-oxidized cellulose nanocrystals(TOCN),using a vacuum-assisted fil-tration method.The morphology and structural characteristics of Fe-MOF and its composite mem-brane were systematically characterized by scanning electron microscopy(SEM),Fourier-transform infrared spectroscopy(FT-IR),and X-ray diffraction(XRD).Optimization experiments revealed that under conditions of pH 7.0 and a shaking speed of 300 r/min,the composite membrane achieved a maximum adsorption capacity of 66.53 mg·g-1 for triazole compounds,with a removal efficiency ex-ceeding 90%within 30 minutes.FT-IR analysis and computational modeling indicated that the prima-ry adsorption mechanism involved chemisorption,including electrostatic interactions,π-π stack-ing,and hydrogen bonding.Even after ten regeneration cycles,the composite membrane main-tained excellent reusability,with a removal efficiency consistently above 80%.This study presents a novel strategy for the development of MOF-based composite membranes for water treatment and dem-onstrates considerable potential for advanced purification of organic pollutants.关键词
