“…SO 4 2– clearly shows a Donnan exclusion effect due to permanent negative charges at the CEM surface. SO 4 2– has slower migration and effective diffusion coefficient than NH 4 + . , Even though the electric force cannot drive Na + migration to the CEM, its concentration potential is large enough to impose a strong force so that Na + carrying a positive charge is adsorbed by the anion in CEM.…”

“…Meanwhile, high-level radioactive wastes are usually disposed of in a way of deep geological disposal (Grambow, 2008). After long-term storage, the disposal facility will eventually be damaged, which will further cause the migration of the radionuclides by groundwater into the surrounding rock medium (Wang et al, 2005;Vanloon et al, 2012). However, for the long-term effective isolation of radioactive wastes, pyrite and magnetite, existing widely and stably in the geological environment, have been considered to reduce the strong mobility of high-valence redox-sensitive radionuclides (U, Se, Tc, and Np) to a lowvalence state with a weak mobility state to make these lowvalence radionuclides adhere to the surrounding rock medium (Bruggeman et al, 2002;Bruggeman et al, 2005;Eglizaud et al, 2006;Naveau et al, 2007).…”
