Two new highly-efficient and eco-friendly biosorbents comprised of magnetite, chitosan Chlorella vulgaris (MCC) or Arthrospira platensis (MCA) were prepared in such a way to be easily separated reused for removing different classes antibiotics as tetracycline (TC), ciprofloxacin (CIP) amoxicillin (AMX) from wastewater. They characterized using SEM, FTIR TGA. Biosorption experiments performed investigate the impact pH, biosorbent dosage, initial antibiotic concentration, contact time, concentration background electrolytes (NaCl, KCl CaCl2) on adsorption. Both biocomposites showed outstanding performance removal. Equilibrium data modelled Langmuir, Freundlich, Temkin, Dubinin-Radushkevich adsorption isotherms, among which first one gave best fit, with maximum TC, CIP AMX capacities 834.0, 394.9, 150.8 mg/g MCA 831.1, 374.2, 140.2 MCC, respectively. To follow time-evolution, pseudo-first-order, pseudo-second-order intraparticle diffusion kinetic models tested, second proved best-fitting one. Thermodynamic parameters revealed that was spontaneous endothermic. regenerated through microwave-assisted treatment repeatedly up four cycles, losing at equilibrium by no >7, 4 9 %, This study suggests both may effective sustainable alternatives commercial adsorbents

Preparation of NH2-MIL-101(Fe) Metal Organic Framework and Its Performance in Adsorbing and Removing Tetracycline

International Journal of Molecular Sciences, Год журнала: 2024, Номер 25(18), С. 9855 - 9855

Tetracycline’s accumulation in the environment poses threats to human health and ecological balance, necessitating efficient rapid removal methods. Novel porous metal–organic framework (MOF) materials have garnered significant attention academia due their distinctive characteristics. This paper focuses on studying adsorption performance of amino-modified MIL-101(Fe) towards tetracycline, along with mechanisms. The main research objectives conclusions are as follows: (1) NH2-MIL-101(Fe) MOF were successfully synthesized via solvothermal method, confirmed through various characterization techniques including XRD, FT-IR, SEM, EDS, XPS, BET, TGA. (2) exhibited a 40% enhancement tetracycline compared MIL-101(Fe), primarily chemical following pseudo-second-order kinetics. process conformed well Freundlich isotherm models, indicating multilayer heterogeneous Thermodynamic analysis revealed spontaneous endothermic reaction. (3) An increased adsorbent dosage temperature correspondingly improved NH2-MIL-101(Fe)’s efficiency, optimal observed under neutral pH conditions. These findings provide new strategies for effective from environment, thus holding implications environmental protection.
