Removal of Cefixime from Wastewater Using a Superb nZVI/Copper Slag Nanocomposite: Optimization and Characterization

Nowadays, hospital wastewater contains a high concentration of toxic pharmaceutical contaminants, posing significant threat to the environment, and human animal life. Cefixime (CFX) is one such contaminant that has detrimental impact on both aquatic terrestrial ecosystems. Therefore, it essential remove this compound using non-toxic environmentally friendly procedures ensure healthy drinking water. In study, low-cost eco-friendly nano adsorbent (nZVI/copper slag) was synthesized characterized FESEM, XRD, EDX, FTIR, zeta potential CFX from wastewater. The Response Surface Methodology (RSM) used evaluate effects experimental factors including dosage (2–10 g/L), pollutant (10–30 mg/L), pH (2–10), contact time (10–50 min) for efficient elimination. optimal conditions (adsorbent dosage: 7.79 g/L, concentration: 19.42 mg/L, pH: 4.59, reaction time: 36.17 resulted in 98.71% removal. adsorption isotherm kinetics data showed pseudo-second-order Langmuir models were appropriate Furthermore, demonstrated 90% elimination after up six repeated cycles regeneration reusability testing. Finally, nZVI/CS can be an effective promising solution removing
