ABSTRACT
The hexavalent uranyl ion {UO2 2+, U(VI)} is an exceptionally stable oxidation state among four different oxidation states [U(III), U(IV), U(V), and U(VI)] of uranium in aqueous systems. Studies using cell and animals reveal that chronic exposure of uranium ion causes the possibility of genetic, reproductive, and neurological disorders on human population due to its radioactivity and chemotoxicity. Schiff base-based chelators are well known for the formation of stable nontoxic complex with uranyl ion; therefore, a great deal of attention has been focused on the Schiff base derivatives and their complexes with uranyl ion. This chapter summarizes the interaction and complexation studies of the uranyl ion with various Schiff base-based acyclic and cyclic chelators.
