Extraction of radionuclides of cerium, europium, cobalt and strontium with Mn3O4, MnO2, and MNOOH sorbents

The paper describes the tests carried out for the extraction of radionuclides 90Sr, 137Cs and 60Cо by manganese oxyhydroxide in order to compare the sorption properties of the respective particles with Sr(II), Cо(II), Cе (III), Eu (III) ions. It was found that the recovery efficiency and the sorption capacity with respect to metal ions decrease in the MnOOH → MnO2 → Mn3O4 series. The tests proved that the extraction of the radionuclides from tap water by MnOOH particles was 53.7%, 83.5% and 93.1%, respectively.
