Sodium aluminosilicate has been synthesized by solution route for use as a sorbent for various radionuclides. It was characterized by XRD, zeta potential, BET surface area, FTIR spectroscopy and site density measurement. Sorption studies of Cs-137, Ba-133 and Eu-154 on synthesized sodium aluminosilicate have been carried out at varying pH (3-10). Sorption of all the metal ions was found to increase with pH of suspension with the saturation value increasing with the oxidation state of metal ion. Effect of Aldrich humic acid (2 mg/l) on sorption was also investigated. In case of Cs-137, the sorption was not affected by the presence of humic acid, while in case of Ba-133 and Eu-154, sorption was enhanced at lower pH and decreased at higher pH in presence of HA. A series of experiments were carried out for Eu-154 sorption on sodium aluminosilicate at various conditions. Sorption of europium was analyzed by different sorption isotherms, viz., Freundlich and D-R isotherm. Thermodynamic data reveal sorption phenomena as endothermic and spontaneous. Studies were further extended to find out effect of diverse ions (Ca2+ and CO32-) on sorption of europium. (C) 2010 Elsevier B.V. All rights reserved.
