Nanocomposites for Decontamination of Multicomponent Technogenic Dilutions
Journal Title: Journal of Nuclear Physics, Material Sciences, Radiation and Applications - Year 2016, Vol 3, Issue 2
Abstract
Employing model solutions we have tested a new technological method of neutralization of multi-metal containing effluences including low radioactive ones. The proposed approach seamlessly combines the positive properties of both physical-chemical methods and nanotechnology using silica-magnetite nanocomposite SiO2/Fe3O4 that is synthesized directly in the man-caused polluted solution (the so-called method of direct sedimentation). The novelty of the method is the absorption of pollutants by the whole volume of synthesized nanoparticles in addition to the absorption of the particles’ surface. After separation of the solid and liquid phases, about 75% Cs, 93% Sr, 97% Cu and 99% Fe+2/ Fe+3 pass from the dispersion medium into a solid phase per one loop. The obtained SiO2/Fe3O4 nanocomposite heated to 1000 °C forms a small size glass phase, which is a reliable matrix for the longterm retention of radionuclides incorporated in the composite’s volume. Thus the approach will allow one to reduce the collected radioactive isotopes to a tiny volume, which means the decrease of land and funds needed to burial radioactive waste.
