In order to create an efficient sorbent for the hydrometallurgical extraction of gallium, germanium from the poor raw materials and for the arsenic removal from the technological solutions a modification of commercially available titanium oxide and its sorption properties studies were performed. The mechanical activation in the high-energy planetary mill and ultrasonication of the aqueous suspension were used for modification of the TiO2. Particle size analysis of modified material performed by dynamic light scattering indicated the presence of particles of nanometer range. According to X-ray diffraction, the proportion of nanoscale fraction is significant. It was found that the mechanical activation and subsequent ultrasonic treatment of TiO2 increases sorption of gallium, germanium and arsenic (III, V), from 10-40 % to 96-97 % at the optimum pH values of the solution.
