Sorption of stable and radioactive Cs(I), Sr(II), Co(II) ions on Ti–Ca–Mg phosphates
2020
In this paper, we studied the features of stable and radioactive Cs(I), Sr(II) and Co(II) ions sorption on Ti–Ca–Mg phosphates. The significant differences in the sorption of macro quantities of stable Cs+, Sr2+ and Co2+ ions and trace concentrations of 137Cs, 90Sr and 60Co radionuclides were found. It has to be taken into account for evaluation the effectiveness of sorbents for the treatment of real liquid radioactive waste. Comparative studies with industrial sorbents have shown that the synthesized in this study mixed Ti–Ca–Mg phosphates are promising materials for one-stage treatment of liquid radioactive waste with complex chemical and radionuclide composition.
