Part of the current theory to explain why using a Nafion film-modified platinum electrode allows for the observation of the redox behavior of lanthanide trifluoromethanesulfonate (triflate) is that Nafion solubilizes the lanthanide compounds, possibly by replacement or equilibrium of ligands with a sulfonate group. Nafion is a cation-exchange polymer with perfluorovinyl ether groups terminated with sulfonate groups onto a tetrafluoroethylene backbone. Triflate is a ligand that closely resembles Nafion perfluorosulfonate side chains. Equivalent weight (EW) is defined as the number of grams of dry Nafion per mole of sulfonic acid groups when it is in the acid form. Our group predicts if the lanthanide triflate interacts with the ion exchange sites on the Nafion film membrane, the membrane with more sites will have a higher current density. This investigation will contribute to the development of lanthanide-based catalysts and the knowledge of Nafion as ion exchange membranes.
