• Note (General): The present study has been carrisd out to establish the final disposal methods for e wastes containing radioactive iodines. In the previous studies, cinnabar (spain) a montmorillonite containing Ag-thiourea complex were selected as the arificial barri materials. In the present report, the adsorption mechanisms of two adsorbents were udied in more detail. Furthermore, various synthetic inorganic ion exchangers were ao examined as the model materials of I$^{-}$ ion adsorbents. The results are summarized afollow : 1. Detail examination for I$^{-}$ ion adsorption behavior of cinnabar (1) In avaible cinnabars, only spain one has an adsorptivity to I$^{-}$ ion. (2) The cinnabar adsorde has the selective adsorptivity to I$^{-}$ ion. (3) It takes 40 days to reach the adsorpti equilibrium. (4) The amount of adsorbed I$^{-}$ ions decreases with the rise of pH, and t desorption of I$^{-}$ ions from cinnadar is not observed. These results suggest that thedsorption of I$^{-}$ ions on cinnabar is not due to the ion exchange but the compo; None
