Abstract

The adsorption of Cs, Sr, Ni, and Co radioactive substitutes onto Yesan clay and zeolite was studied through batch and column tests using Cs, Sr, Ni, and Co as substitutes for radioactive isotopes. Adsorption values of 0.189–1.865 μg/g onto Yesan clay and 0.595–9.055 μg/g onto zeolite were observed, with the radioactive substitutes being almost 100 % adsorbed from the onset of column testing. Adsorption was achieved through ionic bonding. These materials demonstrated suitability for use as backfill or foundation materials for nuclear power plants, radioactive waste disposal facilities, and other radioactive facilities.
