Antibiotic contamination in pharmaceutical wastewater poses environmental and public health risks. This study synthesized a nanocomposite ceramic adsorbent from clay, cow bone powder (hydroxyapatite nanoparticles), human hair for antibiotic removal. The exhibited high mechanical strength (3.6 bar), chemical stability, large surface area (171.32 m2 g-1). Characterization (FTIR, XRD, FE-SEM, BET) confirmed successful nanoparticle incorporation. In vertical fixed-bed column, optimal removal occurred at pH 7, 25 g adsorbent, °C, 40 min contact time. Adsorption was endothermic, following pseudo-first-order intraparticle diffusion models. retained >90% efficiency after 142 regeneration cycles, proving its durability cost-effectiveness.
