We aim to recycle and utilization of eggshell as a biomass waste of human foodstuff. Pure hydroxyapatite nano-particles were prepared using waste eggshell at different temperature of 80 °C (ESHANP) and calcination at the 850 °C (CESHA) adsorbent materials and characterized by some instruments. Sorption studies of

Cd from aqueous waste solutions onto ESHANP and CESHA were performed at different pH solutions, initial ion concentration and contact time. The obtained data were analyzed using some kinetic, diffusion and isotherm models. It can be recommended ESHANP as remediation agent for nuclear waste sites.
