ABSTRACT / SAŽETAK:

Environmental contamination is a significant global concern, demanding effective remediation strategies. This study investigates the efficacy of biowaste-derived carbon material in removing antibiotics amoxicillin and ceftriaxone. Adsorption experiments were conducted at 25°C, and the adsorption behavior was analyzed using various adsorption isotherm models. Our findings reveal a complex process involving both monolayer and multilayer adsorption on the material’s heterogeneous surface. At a concentration of 0.1 mg mL−1, the carbon material exhibited high adsorption capacities of 82 mg g−1 for amoxicillin and 181 mg g−1 for ceftriaxone. The adsorbent was successfully regenerated and reused for at least 10 cycles without significantly impacting its adsorption capacity. These results highlight the potential of biowaste-derived carbon material as an efficient adsorbent for antibiotics, underscoring its promising role in environmental remediation.
