ABSTRACT:
Concentrated liquid waste solutions containing radioactive substances and also complex formers is treated by maintaining pH 5 and adding KMnO.sub.4 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 KMnO.sub.4 added. The excess MnO.sub.4.sup.- is reduced to MnO.sub.2 by addition MnSO.sub.4. MnO.sub.2 separates and adsorbs radionuclides Mn-54, Sb-124, Sb-125 and 65-Zn contained in the solution.
