摘要：

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 radioactive ions on bentonite surfaces was dependent on the pH behavior of the metal ions. A method was proposed to use bentonite as an absorbent of ions from simulated radioactive waste as a treatment step.
