Much information is currently missing in the field of technetium chemistry. The goal of our research is to determine thermodynamic and kinetic parameters for the complexation of Tc(IV) with a series of ligands. This particular work shows the quantification of stability constants for the complexation of Tc(IV) by sulfate using a liquid-liquid extraction (LLE) method. Experiments were carried out over a wide range of ionic strengths (0.1 - 1 m) for extrapolation to zero ionic strength, using the Specific ion Interaction Theory (SIT). Values for enthalpy and entropy of the complexation reactions were determined by conducting these LLE experiments over a range of temperatures.
