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: 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: In this study, carbon molecular sieving (CMS) membranes were fabricated using three different polymer precursor conformations: dilute, semi-dilute, and concentrated. The effects of the precursor conformation on the microstructure of the resulting CMS membranes were characterized by Raman analysis. A novel method combining HR-TEM and FIB systems was proposed to detect the cutoff size of the CMS membranes. The CMS membrane fabricated with a semi-dilute solution exhibited superior gas separation performance, with a high selectivity of H-2/CH4 and hydrogen permeability, surpassing reported permselectivity of other membranes.
