| Περίληψη: | Mercury (Hg) contamination in industrial wastewater poses a significant environmental and health threat. Efficient and targeted removal of Hg(II) is essential to prevent its release into aquatic environments. In this study, sulfur-functionalized mesoporous silica (SFMS) was synthesized via a thiol-ene click chemistry strategy to introduce thiol and thioether groups onto a mesoporous silica framework for Hg(II) capture. SFMS exhibited a strong affinity for Hg(Ⅱ), attributed to dual sulfur coordination sites, enabling efficient removal even under competitive ion conditions.
