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

摘要

The paper describes the tests carried out for the extraction of radionuclides Sr-90, Cs-137 and Co-60 by manganese oxyhydroxide in order to compare the sorption properties of the respective particles with Sr(II), Co(II), Ce (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 -> Mn(3)O(4 )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. (C) 2019 Institution of Chemical Engineers.
