Abstract

The development of the nuclear industry is accompanied by the inevitable formation of radioactive waste that creates a substantial risk of environmental pollution. In the present work, an effective Ca–Mg phosphate sorbents were prepared using dolomite as an inexpensive raw material. It was established that the removal of ⁶⁰Co is predominantly determined by the salinity and pH value of aqueous solution. The highest sorption efficiency was shown for PD-2 sorbent with K_d(⁶⁰Co) changing from 2.44 × 10⁴ to 3.32 × 10³ mL g⁻¹ in the salinity range of 0–50 g L⁻¹. The produced materials are promising for seawater and liquid radioactive waste treatment from ⁶⁰Co radionuclide.
