The effect of solution chemistry on the adsorption of uranium(VI) onto sericite

The adsorption of U(VI) on sericite as a function of contact time, pH, ionic strength, solid contents, carbonate and temperature was investigated by batch techniques. It is observed that the adsorption of U(VI) on sericite was strongly dependent on pH and ionic strength. The presence of carbonate en...

Summary:The adsorption of U(VI) on sericite as a function of contact time, pH, ionic strength, solid contents, carbonate and temperature was investigated by batch techniques. It is observed that the adsorption of U(VI) on sericite was strongly dependent on pH and ionic strength. The presence of carbonate enhanced the adsorption of U(VI) at pH < 6.5, whereas inhibited adsorption was observed at pH > 7.0. The thermodynamic parameters suggested that the adsorption of U(VI) on the sericite was a spontaneous and endothermic process. The results might be important for the application of sericite in U(VI) pollution management.
