Abstract
Fixation of Cs-137, Ce-144, Co-60, Sr-90, Th-240 and U-233 from aqueous and phosphate media on bentonite clay was studied. The fixation of the radioac tive ions on bentonite surfaces was dependent on the pH behavior of the met al ions. A method was proposed to use bentonite as an absorbent of ions fro m simulated radioactive waste as a treatment step.
