Recovery of 60Co and 137Cs with various solid phases from aqueous solutions of different chemical composition

Removal of microamounts of 60 Co and 137 Cs 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 60 Co and 137 Cs with the solid phase of K + , Fe 3+ , and Ni 2+ f...

Description
Summary:Removal of microamounts of 60 Co and 137 Cs 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 60 Co and 137 Cs with the solid phase of K + , Fe 3+ , and Ni 2+ ferrocyanides formed by adding K 4 [Fe(CN) 6 ], Fe(NO 3 ) 3 , and Ni(NO 3 ) 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 NaNO 3 and 3.4 × 10 −5 mol l −1 EDTA.
