Water-based Synthesis of MIL-53(Al) at Room Temperature: An Eff ective Adsorbent for Oxytetracycline (OTC) Antibiotic Removal from Water
MIL-53(Al), a fl exible metal-organic framework, was synthesized by a facile method through a water-based method at room temperature, aligning with the principles of green chemistry. The objective was to investigate its effectiveness in removing pharmaceuticals and personal care products (PPCPs), specifi cally focusing on oxytetracycline (OTC). Our fi ndings revealed that MIL-53(Al) possesses a structure with both micropores and mesopores, with a specifi c surface area of 916 m2/g. MIL-53(Al) notably exhibited a higher OTC adsorption capacity than commercially available powder activated carbon (PAC). The adsorption kinetics followed a pseudo-second-order model, while the Langmuir model accurately described the experimental isotherms for OTC adsorption. MIL-53(Al) outperformed previously reported MOF-based adsorbents with a maximum of 1005 mg/g capacity at pH 7. The fl exible structure induces a breathing effect that signifi cantly improves intraparticle diffusion for OTC, contributing to its adsorption effi ciency. The adsorption of OTC was infl uenced by the solution pH, the acid dissociation constants of OTC, and the charged surface of the adsorbent. Pore fi lling, hydrogen bonding, π-π interaction, electrostatic interaction, and hydrophobic interaction were all associated with the adsorptive interaction between OTC and MIL-53(Al). The MIL-53(Al) also demonstrated good regeneration and reuse, with just a little decreased adsorption capacity after three reuse cycles. These fi ndings indicate that green material MIL-53(Al) has the potential to be an effective adsorbent for removing OTC from water matrices
期刊介绍:
The Chiang Mai Journal of Science is an international English language peer-reviewed journal which is published in open access electronic format 6 times a year in January, March, May, July, September and November by the Faculty of Science, Chiang Mai University. Manuscripts in most areas of science are welcomed except in areas such as agriculture, engineering and medical science which are outside the scope of the Journal. Currently, we focus on manuscripts in biology, chemistry, physics, materials science and environmental science. Papers in mathematics statistics and computer science are also included but should be of an applied nature rather than purely theoretical. Manuscripts describing experiments on humans or animals are required to provide proof that all experiments have been carried out according to the ethical regulations of the respective institutional and/or governmental authorities and this should be clearly stated in the manuscript itself. The Editor reserves the right to reject manuscripts that fail to do so.
