Manganese oxide-based granular sorbent for the removal of strontium radionuclides from radioactively contaminated natural water
A granular manganese oxide-based sorbent was synthesized. One volume of the sorbent decontaminates 125–145 volumes of hardness water from strontium radionuclides to background values of radioactivity. The synthesis includes interaction of MnSO4 with KMnO4 in aqueous medium at [Mn2+]/[MnO4−] = 1.8, followed by the precipitation, aging the precipitate at pH = 11, and calcining it at 160 °C. Characteristics of the sorbent obtained were as follows: the distribution coefficient of the tracer 85Sr radionuclide in 0.01 mol dm−3 CaCl2 solution of 1.6 × 104 cm3 g−1, the batch capacity by Ca2+ of 1.10 mol g−1, and the Sr/Ca pair separation coefficient of 65.
