摘要

The rapid rise in the consumption of medicines and antibiotics over the past decade has led to significant environmental concerns due to their improper disposal. Antibiotics in water sources such as reservoirs, lakes, and groundwater can contribute to the emergence of antibiotic-resistant genes in bacteria, posing substantial risks to both human and animal health. This study aims to evaluate the efficacy of TiC-MXene in removing Ceftriaxone, an extensively utilized antibiotic, from simulated wastewater. The adsorption process was examined by varying different parameters, including temperature and initial concentration, with a focus on the underlying mechanisms. The pseudo-second-order kinetic model provided an in-depth evaluation of the adsorption dynamics, while isotherm analysis revealed multilayer adsorption on the adsorbent surface. Under ideal conditions at pH 7.0, a maximal adsorption capacity of 10.4888 mg/g was achieved with a dosage of 250 mg/L. The material demonstrated stability in various pH conditions, confirming its effectiveness for practical water remediation applications. This research highlights the potential of TiC-MXene in addressing antibiotic contamination and suggests avenues for further investigation into its scalability and application in real wastewater treatment scenarios.
