APPLICATIONS OF FUNCTIONALIZED AZAPHOSPHANES AS NOVEL SCAVENGING AGENTS FOR TCO4-

Azaphosphanes functionalized with different organic substituents have been shown to selectively scavenge (TcO4-)-Tc-99m in the presence of d ifferent concentrations of anions (NO3-, Cl-, OH-) and cations (Pd2+, Pt2+, Fe3+). The fundamental coordination chemistry of the azaphosphan e-based ligand systems with Re included detailed NMR spectroscopic and X-ray structural investigations which has provided important insights that may aid in the application of new azaphosphane ligands for scave nging specific transition metals. The aforementioned studies, clearly show the potential for the application of this new class of main group monomers and polymers in the treatment of liquid wastes containing (T cO4-)-Tc-99 for use in waste management procedures.
