Besides military industry, uranium is also applied to civilian needs. Uranium
compounds are employed in geology (to determine age of rocks), as a pigment for
paints, in analytical chemistry, and for other purposes [1]. However, produced
uranium is mainly consumed by nuclear power plants. Therefore, mining and
processing of uranium ores are important practical tasks. Efficient, accessible, and
cheap methods for the removal of U(VI) compounds from liquid wastes could provide
ecological hygiene in uranium extraction from mineral raw materials. Moreover, the
technique has to cover uranium recuperation in order to prevent appearance of toxic ions
in sources of water supply. Adsorption and ion exchange present a possibility to
decrease the content of U(VI) compounds down to maximum allowable concentration
[2]. The following characteristics for materials are required: significant capacity and
selectivity toward uranium-containing ions, high sorption rate, and facile regeneration.
Currently, attention is focused on change of chemical composition of organic
(particularly biopolymers) or inorganic sorbents.
