Sorption of strontium and yttrium radionuclides from aqueous solutions onto layered double hydroxides of various compositions

Abstract

New experimental results and published data on sorption of strontium and yttrium radionuclides from aqueous solutions onto layered double hydroxides (LDHs) of various compositions are summarized. The effect of double-charged (Mg2+, Ba2+, Sr2+, Cu2+, Zn2+, Ni2+) and triple-charged (Al3+, Fe3+, Nd3+) cations incorporated in the LDH matrix and of anions incorporated in LDH (CO32−, SO42−, NO3−, OH−, Cl−, C2O42−, H2EDTA2−) on the physicochemical properties of this class of compounds, including the ability to sorb strontium and yttrium radionuclides, is examined.
