Abstract
This work investigated the removal of antibiotic ceftriaxone (CEF) from wastewater using mes-oporous copper oxide nanosphere as synthesized resulted from calcination organometallic chelate, and characterized by X-ray diffraction, Fourier-transform infrared spectroscopy, ener-gy-dispersive X-ray spectroscopy, including the Brunauer-Emmett-Teller variable surface area, which was 78.83 m2/g. Scanning electron microscopy got accustomed to quantify the changes on the surface. CEF was accomplished at pH 7, which is the ideal adsorption setting. The thermo-dynamic analysis was done at a variety of temperatures between 25 degrees C and 45 degrees C. The thermody-namic parameters that were obtained highlight a reduction in the adsorption process' endother-mic, random, and spontaneous. The kinetic studies demonstrated that more than one mechanism would affect the diffusion of ceftriaxone from the solution into the copper oxide and that the pseudo-second-order model might provide a better fit of the test findings. According to the iso-therm investigations, the Langmuir model, having the highest adsorption capacity of 127 mg/g, provided the best fit to the isotherm curve. Adsorption's activation energy was also found to be 14.43 kJ/mol, demonstrating that chemisorption process. It was calculated that the adsorption mechanism was endothermic as the negativity of AG degrees was increase with increase the temperature and spontaneous. Also determine thermodynamic parameter AG degrees, AH degrees and AS degrees. A quick and effi-cient method of purifying water was found to be the mesoporous copper oxide nanosphere adsor-bent. Copper oxide nanosphere material has shown promise in the process of removing CEF from aqueous solution. Surprisingly, the synthesized adsorbent displayed a remarkable recyclability of >91.2% up to the sixth cycle. According to the findings, CuO can be employed as a ceftriax-one adsorbent for aqueous mediums at a reasonable cost. On other hand, it was simple to remove the CuO nanosphere from the solution and regenerate it with washing.
