Abstract :
Cefixime is one of the most widely used antibiotics in the world that its presence in the environment, even at low concentrations, causes serious health problems. The current study was conducted with the aim of evaluating the efficiency of copper oxide/graphene oxide nanocomposite functionalized with nanoplatinum as an efficient nano adsorbent in removing cefixime antibiotic from aqueous solutions. For this purpose, the effect of the main operating variables on the efficiency of the adsorbent in antibiotic removal was studied and optimized with the surface response method. Also, the adsorption behavior was investigated by isotherm, kinetic, and thermodynamic studies. The results showed that under optimal conditions, the experimental removal efficiency of cefixime was 99.38±1.25% and the Langmuir maximum adsorption capacity was calculated to be 213.41 mg g-1. Also, thermodynamic studies indicated the adsorption process was spontaneous in nature, endothermic, and reversible. The obtained results showed the potential ability of the presented nanocomposite in removing cefixime from polluted water.
