Resumo
The ability of cerium(IV) hydrogen phosphate Ce(PO4)(HPO4)0.5(H2O)0.5 to adsorb radionuclides was studied. The degree of sorption from aqueous solutions exceeds 95% at pH > 7 for Np(V), at pH > 9 for Sr(II), at pH > 5 for Am(III) and U(VI), and at pH > 2 for Th(IV). The radionuclides are rapidly and quantitatively leached from the sorbent surface in acid solutions; i.e., the sorption is reversible.
