Summary: The removal of zinc ions from water was studied using two types of ordered mesoporous silica (SBA-15 and SBA-16). Both materials were modified with APTES and EDTA through post grafting methods. The modified adsorbents were characterized by various analytical techniques, and the structural integrity was maintained. Optimal adsorption conditions and maximum adsorption capacity were determined through experimental tests, and the regenerated adsorbent showed no significant decline in adsorption efficiency.

Summary: Al2O3 is considered an effective sorbent for capturing lead from flue gas. The study found that different species of lead have high adsorption capacity on the Al2O3 surface, with PbO showing the highest adsorption energy at the Al hollow site. Strong interactions between PbO, PbCl, and PbCl2 molecules with unsaturated Al atoms on the α-Al2O3 (110) surface are responsible for their capture by Al2O3. Overall, Al2O3 has a preference for capturing PbO over other forms of lead.

Summary: This paper investigates the adsorption performance of silver-modified mesoporous materials in removing thiophenic compounds. The results show that the adsorption of thiophene by the sorbents involves S-Ag and pi complexation reactions, and the adsorption efficiency is greatly affected by benzene. XPS analysis reveals that silver interacts strongly with the carrier and forms Ag-O-Si bonds as the active centers for thiophenic compounds. The Mulliken charges of sulfur atoms have an impact on the interactions between silver and thiophene sulfur compounds.

Summary: Terephthalic acid reformed Al/Zn metal organic nanoflake functionalized with trie-thylamine (T-AlZn) exhibits remarkable performance in removing trace lead (II) ions (Pb2+), with an adsorption equilibrium reached within 35 min and a removal rate ≥ 97%. After four regenerations, the decline in removal rates of T-AlZn for Pb2+ is only 16.73%. The adsorption of T-AlZn for Pb2+ follows the Langmuir isotherms model and pseudo-second-order dynamics model, with the utmost adsorption competence of 215.27 mg g-1. T-AlZn adsorbent shows a bright prospect in the adsorption for Pb2+ and is a considerable candidate in the disposal of industrial sewage.

Summary: The removal of phosphate from water is crucial for protecting the ecological environment due to the widespread use of phosphorus fertilizers causing water deterioration. In this study, calcium carbonate-loaded mesoporous SBA-15 nanocomposites with different Ca:Si molar ratios (CaAS-x) were synthesized as effective phosphorus adsorbents. Various characterization techniques were used to examine the structure, morphology, and composition of the nanocomposites. The results showed that increasing the Ca:Si molar ratio improved the phosphate removal capacity, with CaAS-0.55 exhibiting the highest adsorption capacity. The mesoporous CaAS-0.55 nanocomposite demonstrated fast and efficient removal of high concentrations of phosphate in contaminated wastewater.

Summary: Versatile materials for oxidizing As(III) into less hazardous As(V) species have attracted increasing attention. Ti-SBA-15, prepared by coating 7% anatase TiO2 on pre-formed SBA-15, showed efficient adsorption and photo-oxidation of As(III) at different pHs. The presence of TiO2 on SBA-15 promoted reactive oxygen species generation, leading to successful oxidation of As(III). Despite covering only a small percentage of the surface, TiO2 exhibited unprecedented photocatalytic behavior, making it a prominent catalyst for arsenic removal from water.

Summary: Two mesoporous materials, SBA-15 and Zn/SBA-15, were synthesized and tested for quinoline (Q) adsorption in the presence of dibenzothiophene (DBT). The results showed that the SBA-15 adsorbent had a higher removal percentage of Q compared to the Zn/SBA-15 adsorbent, and the Zn incorporation reduced the pore volume and surface area. The highest sulfur removal was observed at a lower temperature for the Zn/SBA-15 adsorbent. Both adsorbents followed the pseudo second-order kinetic model for Q adsorption. The study provides important insights into the application of mesoporous materials for organic pollutant adsorption.
