Series of SBA-15 derived ordered mesoporous silica adsorbents bearing phenylsulfonic, phosphonic groups and their combinations were synthesized by non-grafting approach. Sodium metasilicate was used as precursor for the silica matrix. The materials w

One-pot synthesis of highly ordered SBA-15 type silica-tethered phosphonic acid at weakly acidic pH (3.75) allows for higher loading of phosphonic functionality (up to 33%) without significant deterioration of the mesostructure. In this synthesis sod
