| Abstract: | Five different samples of a new sorbent, modified mesoporous cerium(IV) silicate have been prepared with various mole ratios
of Si/Ce and Cetyltrimethylammonium bromide (CTMABr) as template. XRD, nitrogen sorption, SEM, IR, thermogravimetry and sorption
of radionuclides have been studied. Separation of Hg(II)-Th(IV), Hg(II)-Zr(IV) and Rb(I)-Zr(IV) have been developed on columns
of this novel sorbent. |
