Sorption of Cs(I) and Np(V) onto Clays from the Ostrozhanskoe Deposit (Belarus)

The sorption behavior of Np(V) and Cs(I) on natural and acid-treated bentonite-like clay of Ostro-zhanskoe deposit (Belarus) was studied in a wide range of radionuclide concentrations and pH values of the suspension. The sorption equilibrium with both radionuclides is attained within the first minut...

Description
Summary:The sorption behavior of Np(V) and Cs(I) on natural and acid-treated bentonite-like clay of Ostro-zhanskoe deposit (Belarus) was studied in a wide range of radionuclide concentrations and pH values of the suspension. The sorption equilibrium with both radionuclides is attained within the first minutes of the interac¬tion. The sorption behavior on the untreated and treated clay is similar. Based on the experimental data, ther-modynamic modeling of the Cs(I) and Np(V) sorption onto the clays was performed.
