Adsorption of nickel on rhyolitic Slovak bentonites

Radioisotope of nickel 63 Ni is an important product of the neutron activation in engineering materials of nuclear power plants. Adsorption of nickel on Slovak rhyolitic bentonites Jelšový potok, Kopernica and Lastove was studied using batch method. Radionuclide 63 Ni was used as a tracer. In this p...

Zusammenfassung:Radioisotope of nickel 63 Ni is an important product of the neutron activation in engineering materials of nuclear power plants. Adsorption of nickel on Slovak rhyolitic bentonites Jelšový potok, Kopernica and Lastove was studied using batch method. Radionuclide 63 Ni was used as a tracer. In this paper, we focused on effects of contact time, pH, competitive cations and equilibrium study. This study showed that Slovak rhyolitic bentonites are a promising candidate for removal of radionickel from aqueous solutions.
