Kinetic and thermodynamic aspects of U(VI) and Th(IV) sorption on a zeolitic volcanic tuff

摘要: The sorption behavior of U(VI) and Th(IV) from simulated waste solutions on a zeolitic volcanic tuff Nereju (Vrancea, Romania) has been studied in the absence ionic competition as function contact time, radioactive ions concentration, temperature pH using batch mode technique. effect above-mentioned parameters efficiency was discussed. apparent thermodynamic uranium thorium onto considered were calculated, showing that process is endothermic higher temperatures favor process.
