Abstract

There are shown the results of the nano-sized material sorption characteristics research. Nanotubes with layer structure were used for radioactive uranyl-ions UO2 2+ sorption from water medium. Nanotubes TiO2 were obtained by low-temperature fritting of electroblasting nanopowders. Uranyl-ions were sorbed from uranyl nitrate model solutions of required concentrations and a model solution prepared by reaction of natural mineral autenit with twice-distilled water and HNO3 addition. Research of the UO2 2+ sorption were carried out under static and dynamic conditions at the room temperature. The impact of on the UO2 2+ sorption extent has been studied. Titanium dioxide nanotubes sorption characteristics dependence on mass of sorbent test charge and phases contact time. Analysis of mechanism of UO2 2+ absorption and fixation by nanotubes TiO2 has been accomplished. As a result of immobilization, UO2 2+ are sorbed in nanotube which doesn't require reduction after the sorption. Layer structure of nanotubes becomes significally deformed during sorption. They became fragmented (initial length of nanotubes is 300-600 nm, but after the sorption it comes to 100-130 nm) and unrolled, which increase possibility of radioactive ions capture in the plates of nanotubes. It is shown that titanium dioxide nanotubes with sorption capacity from 36.8 to 92.3% can be used as a very promising material for radioactive water decontamination.
