Abstract
New nanocrystalline titanium-containing sorbents, namely, layered hydrazinium titanate LHT-9, (N2H5)0.5Ti1.87O4 and synthetic ivanyukite-Na Na2K[Ti4(OH)O3(SiO4)3] · 7H2O, possess high sorption capacity towards cations of different valences and, due to their high chemical stability in acidic and alkaline media, provide the purification of liquid radioactive waste of any composition. The calcination of the product of the radionuclide sorption on LHT-9 and ivanyukite at 1000–1200°C yields mineral-like Synroc-type titanate ceramics applicable for long-term immobilization of sorbed radionuclides with a significant (by 17–250 times) decrease in the amount of radioactive waste.
