Eggshell material was used as low-cost and eco-friendly biosorbent for removal of Cs-134, Co-60 and Eu152+154 radionuclides from aqueous solution. The eggshell material was calcined at 500 and 800 A degrees C, and then characterized. Comparative studies on the natural and calcined eggshell for sorption of the three radionuclides were carried out. It was found that, the uptake is in the order: Eu(III) > Co(II) > Cs(I). Further, column chromatography was used in separation of Cs-134, Co-60 and Eu152+154 using 0.15, 0.2 and 0.5 mol/l nitric acid, respectively. Eggshell material can be considered as a promising material for separation of radionuclides from radioactive waste solution.
