Abstract This review is devoted to the study of the adsorption behavior of uranium(VI) using titanium dioxide based sorbents. Uranium pollution of groundwater, soil and rocks is a big problem due to the long-term toxicity of uranium compounds. Waste uranium is a by-product of the enrichment process used in the production of atomic energy, and the danger associated with this is due to the radioactivity of uranium and its toxicity as a heavy metal. The mechanisms of uranium adsorption by titania adsorbents are presented here, depending on the various environmental conditions, as well as the kinetics of adsorption. The influence of the structural characteristics of the sorbents on the adsorption behavior of uranium is depicted. Surface chemistry and sorption activity of titanium dioxide were reviewed. Examples of new advanced sorbents with nanometer dispersion are described and the parameters of adsorption isotherms are also presented. One of the practical tasks of this analytical review is to obtain information for modeling the behavior of uranium in the water/adsorbent system due to anthropogenic pollution.
