The tritium tagged water (HTO) exchange rates between water swollen Nafion-117 membrane and equilibrating water were measured to obtain self-diffusion coefficients of water (D m H 2 O ) in the membrane samples with several multivalent counterions, viz. Ba 2+ , Fe 3+ , Y 3+ , La 3+ , Eu 3+ and Th 4+
The self-diffusion coefficient of water in Nafion-117 membrane in different cationic forms was measured by the transient radiotracer method, which is based on an analytical solution of Fick's second law. The self-diffusion coefficient of water in the membrane was obtained from the analysis of time-d
