        The effect of UV-C irradiation and EDTA on the uptake of Co2+ by antimony oxide in the presence and absence of competing cations Ca2+ and Ni2+

        Leena Malinen,Eveliina Repo,Risto Harjula,Nina Huittinen 한국원자력학회 2022 Nuclear Engineering and Technology Vol.54 No.2

        In nuclear power plants and other nuclear facilities the removal of cobalt from radioactive liquid waste isneeded to reduce the radioactivity concentration in effluents. In liquid wastes containing strong organiccomplexing agents such as EDTA cobalt removal can be problematic due to the high stability of the CoEDTA complex. In this study, the removal of cobalt from NaNO3 solutions using antimony oxide (Sb2O3)synthesized from potassium hexahydroxoantimonate was investigated in the absence and presence ofEDTA. The uptake studies on the ion exchange material were conducted both in the dark (absence of UVlight) and under UV-C irradiation. Ca2þ or Ni2þ were included in the experiments as competing cations totest the selectivity of the ion exchanger. Results show that UV-C irradiation noticeably enhances thecobalt sorption efficiency on the antimony oxide. It was shown that nickel decreased the sorption ofcobalt to a higher extent than calcium. Finally, the sorption data collected for Co2þ on antimony oxidewas modeled using six different isotherm models. The Sips model was found to be the most suitablemodel to describe the sorption process. The Dubinin-Radushkevich model was further used to calculatethe adsorption energy, which was found to be 6.2 kJ mol1
