A novel adsorbent, amine-functionalized porous silica-coated iron oxide nanoparticles (Fe3O4@SiO2-NH2) was prepared for the removal of cefixime (CFX) and ceftriaxone (CFT) from water. The adsorbent then characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy, transmission particle size, surface area pore size analysis. amine functionalized silica coated are 110 nm, 1073 m2/g 40 Å, respectively. effect dose, concentration, time duration, temperature pH were evaluated. At optimum conditions, efficiency CFX CFT found to be 94.53% 88.3%, adsorption data onto Fe3O4@SiO2-NH2 fully fitted with Freundlich isotherm followed pseudo-2nd order kinetic model. has strong interaction through hydrogen bonding. regenerated reused 30 times, it that dropped only 10%. Owing high easy preparation method, could used as an efficient nano-adsorbent antibiotics other emerging contaminants wastewater.
