Sorption of radionuclides on mesoporous Sn(IV) silicate: a new sorbent

Four different samples of mesoporous Sn(IV) silicate with varying mole ratio of Si/Sn have been used to study the sorption behavior of 18 radionuclides on these materials. Ion-exchange capacity, SEM, distribution coefficient and chemical stability have been studied and discussed. Separation of T1(I) from Th(IV), Cs(l) from Th(IV) and Cs(I) from Zr(IV) have been developed on columns of this sorbent.
