<p>Concentrated liquid waste solutions containing radioactive substances and also complex formers is treated by maintaining pH 5 and adding KMnO4 to oxidize complex formers, and solidifying and embedding the resultant solution in a binder. Dilute solutions are also maintained at a pH of 5 and excess KMnO4 added. The excess MnO4- is reduced to MnO2 by addition MnSO4. MnO2 separates and adsorbs radionuclides Mn-54, Sb-124, Sb-125 and 65-Zn contained in the solution.</p> |
