“…27,28,33 Previously, SBA-15 was primarily obtained using expensive tetraethyl ortho silicate as the silica precursor; therefore, an inexpensive sodium silicate as a source of silica has become an attractive option. 29,30,34 Using another source of silica than in our previous studies (i.e., solution of sodium silicate instead of solid salt) led to further characteristics of the samples especially of "bare" SBA-15. It provided particles of the nanosize that agglomerated into larger formations.…”

“…The pure SBA-15 (sample SBA ) was prepared according to previous publications with some modifications. , Briefly, 2.5 g of surfactant (Pluronic 123) was dissolved in 70 mL of 2 M HCl during constant stirring for 30 min at room temperature giving a transparent solution. 0.05 mol of SS, separately dissolved in 20 mL of water, was added in a thin stream to the resulting clear mixture.…”

Per- and polyfluoroalkyl substances (PFAS) are very stable and ubiquitously distributed in terrestrial and aquatic environments, and treatment and remediation techniques for the removal of PFAS are urgently needed. In this study, mesoporous silica matrix SBA-15 grafted with alkyl amino groups was used to remove perfluorooctanoate (PFOA) from aqueous solutions. The amino groups were grafted onto SBA-15 by the condensation of alkyl amino silanes. The synthesized adsorbents were studied by SEM, TEM, IR, low-temperature nitrogen sorption, and XRD. The solid-state and liquid 19F NMR spectroscopy, EDX, and LC-MS/MS results showed high adsorption efficiency and rapid reaction kinetics. In freshly prepared solutions and on the surface of the sorbents, the presence of PFOA micelles was observed. Furthermore, the introduction of amine-containing groups into the structure of the sorbent allows the sorption of up to 649 mg/g of PFOA from solutions. Results showed that the protonated surface amino groups and PFOA interacted electrostatically. The obtained results open perspectives for producing adsorbents for facile extraction of PFAS.

“…The functionalization of the surface of mesoporous materials with organic or inorganic functional groups leads to new physical and chemical properties [45] and can enhance the adsorption capacity toward heavy metals [58]. Thus, [59] showed that among a series of adsorbents of SBA-15-type with different ligands, neat SBA-15 showed the lowest adsorption capacity toward rare earth elements and heavy metals.…”

Rapid technological, industrial and agricultural development has resulted in the release of large volumes of pollutants, including metal ions, into the environment. Heavy metals have become of great concern due to their toxicity, persistence, and adverse effects caused to the environment and population. In this regard, municipal and industrial effluents should be thoroughly treated before being discharged into natural water or used for irrigation. The physical, chemical, and biological techniques applied for wastewater treatment adsorption have a special place in enabling effective pollutant removal. Currently, plenty of adsorbents of different origins are applied for the treatment of metal-containing aqueous solution and wastewater. The present review is focused on mesoporous materials. In particular, the recent achievements in mesoporous materials’ synthesis and application in wastewater treatment are discussed. The mechanisms of metal adsorption onto mesoporous materials are highlighted and examples of their multiple uses for metal removal are presented. The information contained in the review can be used by researchers and environmental engineers involved in the development of new adsorbents and the improvement of wastewater treatment technologies.
