- Abstract
Nanoparticles of metal oxides with high specific surface area were tested for separation of selected radionuclides (241Am, 60Co, 137Cs and 90Sr) from simulated spent decontamination solutions containing citric acid. The following materials, prepared via photoinduced synthesis, were tested: NiO, NiO/TiO2 and ZnO:Cu. Buffer solutions with concentration of citric anions 0.01 mol l−1 were used in the tests. Sorption properties were investigated in pH range 2-12. Additionally, the influence of surfactants on the sorption was studied. The results obtained show the highest retention of radionuclides for nanoparticles of NiO/TiO2 at basic pH.
