    Sorption of UO2+2 Onto Calcium Carbonate Nanoparticles

    • Calcium carbonate nanoparticles were prepared in the presence of poly(styrene sulfonate) (PSS). The samples were characterized by scanning electron microscopy (SEM). The sorption of UO2+2 onto CaCO3 nanoparticles was investigated as a function of pH, ionic strength and temperature under ambient conditions using batch technique. The results indicate that sorption of UO2+2 onto CaCO3 nanoparticles increases with increasing pH and decreasing ionic strength. With increasing temperature, maximum adsorption of UO2+2 increases. The thermodynamic data indicate that the sorption of UO2+2 onto CaCO3 nanoparticles is an endothermic and spontaneous process.
