Two samples of mesoporous MCM‐41 have been prepared in acidic and basic conditions with cetyltrimethylammonium bromide (CTAB) as template and characterized by powder X‐ray diffraction and N 2 adsorption‐desorption measurement to confirm the ordered mesoporous structure. Sorption of 21 toxic metal ions on these sorbents has been studied and discussed. The results show that distribution coefficient of Ba(II), Fe(III), Th(IV) on the synthesized MCM‐41 in basic condition and Cu(II), Pb(II), Zr(IV) on the synthesized MCM‐41 in acidic condition has been enhanced.
