The paper presents the results of 106Ru radionuclide behavior regularities study in aqueous solutions in a wide pH range by ultrafiltration, ion exchange and centrifugation methods. The regions of 106 Ru various species existence in solution have been established: cationic 106 Ru species at pH 4.2. A characteristic feature of the studied solutions is the formation of non-ionic particles by microconcentrations of 106 Ru via pseudocolloids at lower pH values as compared to ruthenium solutions with a concentration of 10 -6 –10 -4 mol/dm 3 . The established regularities of the behavior of ruthenium radionuclides can be utilized to increase the efficiency of ion exchange and membrane separation methods at nuclear and radiation facilities for technological solutions and liquid radioactive waste treatment.
