ABSTRACT
In the present work nano-hydroxyapatite/ Carboxymethyl Cellulose (n-HApCMC) composite was synthesized by precipitation method and was characterized by Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD) crystallography and scanning electron microscopy (SEM). The n-HApCMC composite was tested for the adsorption of Mercury from aqueous solution and compared its removal capacity with nano-hydroxyapatite (HAp). Effect of various physico-chemical parameters such as pH, adsorbent dose, contact time, initial metal ion concentration and temperature on adsorption of metal ions onto n-HApCMC composite was investigated. The adsorption process followed pseudo-second order kinetics and intra-particle diffusion model. 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.
