Abstract

Ion mobilities of different99mTc- and99Tc chelates prepared by reduction of pertechnetate by Sn(II) in the presence of citric, malic, tartaric, gluconic, and α-hydroxyisobutyric acid as ligands have been measured by means of electrophoresis without supporting material. All the chelates investigated proved to be anions in the pH range of 2–7. Both the Tc(V)- and Tc(IV) compounds with the same ligand including the99mTc preparation show identical ion mobilities and dissociation characteristics.
