| Özet |
| The increasing presence of antibiotics like tetracycline (TC) in aquatic systems poses serious environmental concerns, requiring efficient and sustainable removal strategies. In this study, boron carbide/chitosan (BCS) composites were synthesized via mechanical alloying using varying chitosan ratios (10–40 %) and milling times (5–15 h) to assess their TC adsorption performance. The composites were extensively characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), Brunauer–Emmett–Teller (BET) surface area analysis, scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDS), and zeta potential measurements. The composite containing 20 % chitosan milled for 5 h (BCS0.2) exhibited the highest adsorption efficiency, with a monolayer adsorption capacity of 15.26 mg g−1, a surface area of 10.83 m2 g−1, and an average pore size of 3.14 nm. Adsorption equilibrium was reached in 300 min, and the kinetic behavior followed the Elovich model, implying chemisorption, while equilibrium data fit best with the Temkin isotherm model. TC adsorption decreased notably at pH < 4.3 due to surface charge interactions. Thermodynamic evaluations revealed that the process is endothermic and non-spontaneous. Tap and drinking water matrices slightly enhanced TC adsorption compared to distilled water. Although the reusability of the composite declined over cycles, 43.26 % removal was retained after the third cycle using 0.5 M NaOH. These findings demonstrate the potential of BCS composites as efficient and reusable adsorbents for antibiotic-contaminated water treatment. |
