In the present work nano-hydroxyapatite (n-HAp)/Carboxymethyl Cellulose (CMC) composite was synthesized. The n-HApCMC composite was tested for the adsorption of Chromium from aqueous solution and compared its removal capacity with nano-hydroxyapatite (n-HAp). Equilibrium data were fitted well in the Langmuir and Freundlich isotherm models. The thermodynamic analysis also established that the adsorption process was endothermic and spontaneous.
Keywords: Adsorption, Heavy metals, Isotherm, Nano-hydroxyapatite/Cellulose
