Synthesis of SBA-15 Type Organosilica Sorbents Using Sodium Metasilicate and Phosphonic Acid Residues

The direct template method was used for the synthesis of mesoporous organosilica sorbents of SBA-15 type with phosphonic acid groups using sodium metasilicate (SS) as a source of silica. The presence of functional groups in the synthesized samples was confirmed by IR spectroscopy and elemental analy...
