Y. Takahashi et al., HYDRATION STRUCTURE OF EU-III ON AQUEOUS ION-EXCHANGE RESINS USING LASER-INDUCED FLUORESCENCE SPECTROSCOPY, Chemical communications, (2), 1997, pp. 223-224
Ca. 2 and > 5 molecules of hydrated water are removed from the inner s
phere of Eu-III on strongly and weakly acidic ion-exchange resins, res
pectively, showing the different mechanisms between ion-exchange react
ions occurring on these two types of resins.
