This paper relates to the problem of drinking water contaminants from soluble heavy metals. Proposed for sorption purification of water using titanium dioxide, which was synthesized by chemical and electrochemical methods. The synthesized products are nanostructured compounds x-ray amorphous and crystalline titanium dioxide. Adsorbed and crystallization water is removed by heating from sorbent to 110 °C in air. To stabilize the amorphous structure of the sorbent calcined at 600 °C. At the same time formed titanium dioxide, containing two crystalline phases: anatase and rutile. Sorption properties with respect to the soluble ions of Fe+2/Fe+3 and Mn +2 was investigated in static mode, using titanium dioxide powders synthesized in acidic, neutral and alkaline media. Pre-sorbents were subjected to activation by the action of ultrasound (22 kHz, 0.15 W/cm2). The best results were obtained using a titanium dioxide powder, which was synthesized in an alkaline environment. For practical use of sorbent needed to achieve two objectives: to transfer the sorbent powder into pellets with preservation of the active surface, resistant to water and to develop a system of regeneration of used sorbent. In this paper we studied the water resistance of granular titanium dioxide and how it can regenerate after purification.
