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: SBA-15 mesoporous silica is a suitable drug carrier material due to its structural characteristics and biocompatibility. Spray drying is an efficient method to obtain SBA-15 particles, and co-spray drying with drugs improves drug loading, dissolution, and stability. The resulting drug-loaded SBA-15 particles have defined size, high sphericity, and easy handling, making them suitable for pharmaceutical formulations.

Summary: This study investigated the incorporation of high aluminum loading in the SBA-15 silica structure. Different Si/Al molar ratios were evaluated, and the mesoporous structure of the materials was demonstrated. The presence of higher aluminum content compromised the structural order, but did not affect the mesoporous structure. Higher aluminum loading increased the quantity of acid sites, and aluminum incorporation was confirmed through spectroscopic analysis.

Summary: Albendazole is a poorly water-soluble crystalline drug, and mesoporous materials offer a promising strategy to increase its solubility. This study developed quantification techniques combining chemometric models with UV and FT-IR spectra to determine the drug loading content in mesoporous materials without drug release. The results showed that both UV and FT-IR models achieved excellent drug loading predictions, with high correlation coefficients and low errors. These techniques contribute to improving the time and cost of drug loading determination.

Summary: Naproxen was impregnated into mesoporous SiO2 SBA-15 using the Supercritical Solution Impregnation (SSI) technique. The percentage of naproxen impregnated decreased with increasing CO2 density and with the addition of ethanol, ethyl acetate or menthol. The impregnated naproxen on SiO2 became amorphous and showed interaction with SiO2 support. Release tests showed a sustained release system with a slower rate compared to pure naproxen due to the interaction and diffusion of the drug.

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: 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.
