Sorption of cesium, strontium, and yttrium radionuclides from the aqueous phase on layered double hydroxides
Sorption of 137 Cs, 85,90 Sr, and 90 Y from aqueous solutions on the solid phase of layered double hydroxides (LDHs) and layered double oxides (LDOs) of various compositions was studied. On the solid phase of Mg-Al and Cu-Al LDHs and Mg-Al LDO, the Sr and Cs radionuclides are very weakly sorbed from...
