Titanate nanofibers as intelligent absorbents for the removal of radioactive ions from water

Layered titanate nanoribers can absorb bivalent ions from waste water via an ion exchange process. The sorption induces a considerable deformation of the layered structure, thus trapping the cations in the fibers permanently. Therefore, the fibers are desirable sorbents for the removal of toxic, radioactive Ra2+ and Sr2+ ions from water and subsequent safe disposal thereof.
