摘要:
Removal of microamounts of Co-60 and Cs-137 from different aqueous solutions, included NPP trap waters and simulated NPP bottom residues, by coprecipitation with various solid phases was studied. It was showed that coprecipitation of Co-60 and Cs-137 with the solid phase of K+, Fe3+, and Ni2+ ferrocyanides formed by adding K-4[Fe(CN)(6)], Fe(NO3)(3), and Ni(NO3)(2) ensures almost 100% removal of both radionuclides from simulated NPP trap waters and more than 99% from simulated NPP bottom residue containing simultaneously up to 400 g l(-1) NaNO3 and 3.4 x 10(-5) mol l(-1) EDTA.
