Abstract

Nanoscale titanium dioxide modifications with anatase and η-TiO2 structures have been obtained by the sulfate method. Bands characteristic of the η-TiO2 phase are selected in the Raman and IR spectra of the samples containing this phase. A study of the properties of synthesized samples applying a complex of physicochemical methods revealed that nanocrystals in the samples containing phases of different modifications differ in size, structure, and surface composition. It is shown that the abovementioned nanoscale modifications are characterized by the efficient sorption of As (V), Bi (III), and V (V) from aqueous media; the degree of sorption depends on the size and structural form of nanocrystals.
