Technetium Complexation

Abstract: Technetium-99, a predominantly man-made element, can be found in the environment because of nuclear testing, the nuclear reprocessing industry, and nuclear accidents. Tc-99 is found in aqueous systems known to contain halide salts. Although Tc(VII) is thought to be the primary oxidation state of the metal under oxic conditions, Tc(IV) can also be found in the environment due to different reductive pathways. Quantification of thermodynamic parameters associated with the formation of the Tc(IV)-ligands complexes in solution is important to understand the metal behavior in relevant environmental water systems. We will discuss methodologies to obtain such data and relevant results.
